Built for teams who text buyers and clients daily

A CRM with SMS where every text respects consent, lands on the record, and does not blow up the carrier bill.

Business SMS has become a required channel in sales, service, and client communication. Most CRMs treat SMS as a bolt-on with weak consent capture and no 10DLC registration guidance. Strkr Messaging ships SMS and MMS natively with consent tracking, 10DLC registration, keyword opt-out, bulk sends, and Strkr AI drafting.

What this audience is actually dealing with

The pains that bring buyers here.

Business SMS looks easy from the outside and gets complicated the moment the first message sends. Carrier filtering, 10DLC registration, consent capture, keyword compliance, bulk-send pricing, inbound routing. The cards below are the pains that show up when SMS is bolted onto a CRM instead of built in.

Carrier filtering blocks sends

The first bulk SMS send gets 60 percent carrier filtered.

US carriers (AT&T, T-Mobile, Verizon) heavily filter unregistered or lightly-registered SMS traffic. A team sending bulk SMS without 10DLC registration or with weak campaign vetting sees 30 to 70 percent of sends filtered to spam folders. Strkr handles 10DLC registration natively through the admin console with carrier-vetted campaign setup.

Consent capture is missing

The CRM texts a lead who never opted in to SMS.

TCPA compliance requires explicit opt-in consent before SMS outreach. Most CRMs do not track consent per contact. Reps send texts without visibility into whether the recipient actually consented, which creates class-action exposure. Strkr tracks consent per contact with source and timestamp, and blocks sends to non-consenting contacts.

Keyword opt-out does not work

Prospect replies STOP, the next bulk send includes them.

TCPA requires honoring STOP, QUIT, UNSUBSCRIBE, END, and CANCEL keywords. Most CRM SMS integrations do not consistently honor the keywords across campaigns. Strkr honors every keyword immediately workspace-wide, logs the opt-out event, and suppresses the contact from all future sends automatically.

Threading breaks the conversation

Rep replies and the inbound reply creates a new thread.

When a rep sends an SMS and the recipient replies, the reply should thread to the original conversation. Many CRM SMS integrations create a new activity record for each inbound message instead of threading. Strkr threads inbound replies to the ongoing conversation so the rep sees the full exchange on the contact record.

Bulk pricing is opaque

The SMS invoice arrives and nobody knows what drove it.

Business SMS pricing has multiple components (per-message, per-segment, per-carrier markup, 10DLC monthly fee). Many CRM SMS integrations charge an opaque per-message rate. Strkr Messaging publishes the full pricing model openly: base plus markup disclosed per message, segment, carrier fee passthrough, and 10DLC monthly fee.

MMS is a different product

The CRM supports SMS but not image or document attachment.

Many business SMS integrations support text-only. Service motions (sending receipts, photos, invoices via text) and real-estate motions (sending property photos) need MMS. Strkr supports SMS and MMS on every paid tier with configurable attachment-type and size handling per carrier.

The SMS primitives

What Strkr Messaging ships for business SMS.

Strkr Messaging combines the SMS and MMS channels with the native CRM data model, the Strkr AI drafting stack, and the compliance surface in one product. The cards below are the primitives available on every paid tier.

Two-way SMS

Send and receive text messages per rep.

Reps send and receive SMS from the contact view, the deal view, or the inbox-style messaging surface. Inbound messages route by caller ID with account-owner routing fallback. Outbound sends use the rep's assigned SMS number. The two-way flow is the base unit of the SMS motion.

MMS support

Images, documents, and multimedia attachments.

MMS support covers images (JPG, PNG), documents (PDF under 5 MB), and short video clips. Attachments respect per-carrier size limits with transparent error messages when a send exceeds the limit. The pattern is especially useful for service (receipts, photos), real estate (property images), and healthcare (appointment reminders with intake forms).

Consent capture

Explicit opt-in with source and timestamp.

Consent capture tracks every opt-in event with the source (form submission with SMS checkbox, verbal consent captured in a call summary, imported consent with claimed source and date), the timestamp, and the user who captured. Sends to non-consenting contacts are blocked by default with configurable admin override for specific regulated scenarios.

Keyword opt-out

STOP, QUIT, END, CANCEL, UNSUBSCRIBE honored.

Every incoming SMS is scanned for opt-out keywords (STOP, QUIT, END, CANCEL, UNSUBSCRIBE). A match immediately suppresses the contact from all future SMS workspace-wide, logs the opt-out event, and sends the carrier-standard confirmation reply. The pattern satisfies TCPA requirements for opt-out honoring.

10DLC registration

Carrier-vetted campaign setup from the admin console.

The 10DLC registration flow runs through the admin console: register the brand, submit campaigns with use-case descriptions, provide sample messages, pay the one-time registration fee and the monthly campaign fee. Approved campaigns unlock substantially higher throughput and dramatically reduced carrier filtering. Strkr handles the carrier-side vetting through the underlying Messaging stack.

Bulk sends

Up to 10,000 messages per batch with throttling.

Bulk sends dispatch up to 10,000 personalized messages per batch with per-message variable substitution. Throttling respects per-rep hourly limits (default 100 per hour) and 10DLC campaign-level daily caps. The send cadence spreads across the throughput window rather than attempting the full batch instantly, which protects the sender reputation and matches the carrier-expected pattern.

Strkr AI drafting

AI drafts the SMS message with contact context.

Strkr AI drafts SMS messages from a brief and the contact context (recent activity, open deal, prior exchange). The rep edits for 10 seconds and sends. The pattern is especially useful for high-volume outbound where cold-text quality degrades through the day; the AI maintains quality across hundreds of sends.

Auto-logging

Every message lands on the contact timeline.

Every inbound and outbound SMS lands on the contact's activity timeline with sender, recipient, timestamp, and content. The timeline interleaves SMS with emails, calls, meetings, and other activities so the rep sees the full conversation history in one chronological view.

Templates

Canned SMS messages with variable substitution.

SMS templates insert canned messages with variable substitution (contact first name, account name, deal name, meeting time). Templates are workspace-shared or personal. The pattern replaces the copy-paste from a shared doc that most teams fall into. Templates are especially useful for appointment reminders, order confirmations, and standard follow-ups.

The compliance surface

The controls that keep SMS defensible.

SMS is one of the most litigated channels in US business communication. TCPA class actions have cost businesses millions in settlements. The compliance posture below is designed to keep teams defensible under TCPA, PECR, and GDPR scrutiny.

TCPA express written consent

Every contact has a traceable consent record.

TCPA requires express written consent for marketing SMS. Strkr tracks every consent with source (form, verbal captured in call, imported with chain of custody), timestamp, and user who captured. The consent record is retrievable per contact. For class-action defense, the consent record is the primary artifact; Strkr's structured capture makes defense substantially stronger than the ad-hoc patterns most CRMs use.

Calling-window enforcement

Sends restricted to allowed windows per jurisdiction.

TCPA restricts marketing SMS to allowed hours (8 AM to 9 PM local recipient time). Strkr blocks sends outside the window automatically. Admin overrides are available for specific regulated motions (transactional messaging, service-driven alerts) with the override reason logged. The pattern avoids the TCPA calling-window violation that is one of the most common class-action triggers.

Opt-out honoring across campaigns

A STOP from any campaign suppresses all future sends.

When a contact replies STOP (or any variant: QUIT, END, CANCEL, UNSUBSCRIBE) to any SMS, the contact is suppressed from all future sends workspace-wide, not just the originating campaign. The pattern avoids the common failure where a contact opts out of a campaign but keeps receiving sends from other campaigns, which is a TCPA violation.

10DLC campaign vetting

Approved campaigns with carrier-vetted use cases.

The 10DLC campaign vetting process requires detailed use-case descriptions, sample messages, consent flow documentation, and brand verification. Strkr handles the vetting through the admin console. Approved campaigns unlock higher throughput (up to 60 messages per second per campaign depending on carrier and tier) and reduced carrier filtering. Unapproved sends either throttle heavily or fail with explicit carrier-filtering errors.

DNC registry respect

Internal DNC list enforced across campaigns.

Strkr maintains an internal DNC list workspace-wide. Contacts flagged as DNC through any mechanism (STOP keyword, manual flag, imported list) are suppressed across all future SMS and voice outbound. The admin can review the DNC list, add contacts manually, or remove entries after appropriate review. The pattern avoids the common failure where DNC flags live in one tool but do not propagate across the stack.

Audit log

Every send, consent, opt-out, override logged.

The audit log captures every send, every consent capture, every opt-out, every admin override, every DNC flag. The log is read-only (immutable for class-action defense) and the compliance officer can export for regulatory review. The combined posture satisfies the audit expectations of TCPA class-action defense and the stricter SOC 2 Type II controls.

The high-volume motion

Running bulk SMS at scale without blowing up carrier reputation.

Business SMS at scale (thousands of sends per day, bulk-send campaigns, appointment-reminder volumes) requires specific operational discipline. The cards below are the controls that keep high-volume SMS working at scale.

Throughput tiers

Starter, standard, enterprise throughput per 10DLC tier.

Throughput per 10DLC campaign scales with the campaign vetting tier: starter campaigns ship 10 messages per second, standard 40, enterprise 60 or higher depending on carrier. Teams running high-volume motion register at the appropriate tier during 10DLC setup. The pattern avoids the common failure of trying to run enterprise-volume SMS on a starter campaign and hitting throughput caps.

Carrier delivery monitoring

Deliverability dashboard per carrier.

The SMS deliverability dashboard shows delivery rate, filter rate, and error distribution per carrier (AT&T, T-Mobile, Verizon, US Cellular, international carriers). Trends surface filtering drift before it becomes a workspace-wide outage. The admin runs the dashboard weekly as part of SMS-ops hygiene.

Sender rotation

Multiple numbers per campaign for throughput and risk distribution.

For teams running very high volumes, the admin can configure multiple numbers per campaign so throughput distributes across the number pool. The pattern spreads carrier-reputation risk: a single number trending toward filtering does not affect the full campaign. Rotation is configurable per campaign.

Content filtering awareness

Admin flags that trigger carrier filtering.

Certain content patterns trigger carrier filtering (specific URLs, specific keywords tied to prohibited verticals, excessive capitalization, suspicious short-link patterns). Strkr's content-filtering preview flags high-risk patterns before send so the admin can revise. The pattern avoids the common post-send surprise where a well-intentioned campaign gets filtered.

Short-link rewriting

Links rewritten to a brand-matched short domain.

Short-link rewriting replaces generic URL shorteners (bit.ly, tinyurl) with a brand-matched short domain. The pattern reduces carrier-filtering risk because carriers filter aggressively on known-abused shortener domains. The rewriting tracks click-through for attribution without the generic-shortener filtering risk.

Per-campaign spend caps

Admin sets daily and monthly spend ceilings.

Per-campaign spend caps limit the daily and monthly SMS spend per campaign. The pattern avoids the budget-surprise failure where a runaway automation drives thousands of extra sends. Caps trigger send blocking with admin notification; the admin reviews and either lifts the cap or lets the campaign pause.

How teams use Strkr

How SMS-heavy teams run Strkr today.

The patterns below are motions live on customer accounts right now. The common thread: teams running SMS at material volume saw measurable lift on both compliance posture and deliverability after moving to Strkr Messaging.

32-rep inside-sales team, cold SMS outbound

10DLC registration lifted inbox placement from 42 to 94 percent.

A 32-rep inside-sales team had been sending cold outbound SMS without 10DLC registration and seeing 58 percent of sends filter to spam. The Strkr admin ran the 10DLC registration (brand + two campaigns) over two weeks. Post-approval, inbox placement climbed from 42 percent to 94 percent. Response rates on cold SMS lifted from 2 percent to 11 percent as the sends actually reached inboxes.

18-advisor real-estate team, listing-engagement SMS

MMS photos drove listing-tour bookings up 40 percent.

An 18-advisor real-estate team sends MMS photos of new listings to interested buyers. Pre-Strkr the agents sent via personal cell phones with no logging. The move to Strkr with MMS, auto-logging, and consent tracking replaced personal-cell texting with structured SMS. Listing-tour bookings from SMS engagement lifted 40 percent because the pattern became measurable and tunable.

24-advisor wealth firm, client-communication compliance

Compliance review of SMS reduced from manual to spot-check.

A 24-advisor wealth firm requires 7-year retention of all client communications including SMS. Pre-Strkr the advisors texted from personal cells; the compliance officer manually collected quarterly screenshots. Strkr's native SMS with per-record retention and audit log replaced the manual process. The compliance officer runs spot-checks on the Strkr audit instead of full-text collection, which freed roughly 20 hours per quarter.

60-rep service team, appointment reminders

No-show rate dropped from 18 to 7 percent.

A 60-rep service team sends appointment reminders via SMS. Pre-Strkr the reminders went manual with uneven coverage. Strkr Flows plus SMS fire reminders at 48 hours, 24 hours, and 2 hours before each appointment with templates and MMS where appropriate. No-show rate dropped from 18 to 7 percent. The service director attributed the lift to the consistency of the reminder cadence and the inbound-reply handling that let customers reschedule via text.

12-rep SMB, two-way customer support SMS

Response time to customer SMS dropped from 2 hours to 20 minutes.

A 12-rep SMB support team moved from email-only support to adding two-way SMS as a support channel. Strkr's SMS routing (match to account-owner first, then skills-based) got inbound customer SMS to the right agent in under 2 minutes. Response time to customer SMS dropped from the previous 2-hour email baseline to 20 minutes on SMS. CSAT scores climbed from 4.1 to 4.6 as the responsive channel became the preferred option for most customers.

Common questions

What buyers in this bucket ask most.

What is 10DLC and does Strkr handle the registration process?

10DLC (10-Digit Long Code) is the US-mandated framework for business SMS traffic. Businesses register their brand and their specific SMS campaigns (use case, sample messages, consent flow) with carriers via The Campaign Registry (TCR). Approved brands and campaigns get substantially higher throughput and reduced carrier filtering. Unregistered or lightly-vetted SMS gets heavily filtered. Strkr handles the registration workflow through the admin console: brand registration, campaign submission with use-case description and sample messages, consent flow documentation, carrier-side vetting. The process typically takes 7 to 14 business days for approval. We provide registration templates for the common use cases (sales outreach, appointment reminders, two-factor codes, account alerts, surveys) and guide the admin through the brand-verification steps. The one-time registration fee and monthly campaign fee pass through transparently in the Strkr Messaging line.

How does Strkr handle TCPA class-action risk?

TCPA class-action risk is one of the biggest exposures in business SMS. The posture: structured consent capture per contact with source, timestamp, and chain of custody; immediate opt-out honoring across the workspace on STOP keyword variants; calling-window enforcement to prevent after-hours sends; audit log of every send, consent, opt-out, and override that is immutable for class-action defense; DNC registry respect; 10DLC campaign vetting that establishes legitimate business use. The combined posture is substantially stronger than the ad-hoc patterns most CRMs use, and the audit log is specifically designed to produce the artifacts a TCPA class-action defense needs. For teams with specific compliance review requirements, we provide the full compliance documentation and audit sample for procurement and legal review.

Can Strkr send MMS with images, documents, and video?

Yes. MMS support covers images (JPG, PNG, GIF up to roughly 1 MB per carrier limits), documents (PDF up to roughly 5 MB), and short video clips (MP4 up to roughly 1 MB). The exact size limits vary by carrier; Strkr returns transparent error messages when a send exceeds a carrier's limit. Common use cases include receipt-photos (service motion), property-images (real estate), appointment-intake forms (healthcare), and promotional-visual campaigns. The MMS per-message cost is higher than SMS (typically 2x to 3x) and the pricing is disclosed openly in the Strkr Messaging documentation.

How does the pricing work for high-volume SMS?

Strkr Messaging pricing has three components disclosed openly. Base: a flat workspace subscription that covers up to a specified monthly message volume. Per-message markup: a small markup above the carrier's per-message cost (disclosed in the pricing documentation). Carrier-fee passthrough: the per-message carrier fee that US carriers assess for 10DLC traffic (varies by carrier and campaign tier, passed through at cost). For teams running very high volume (over 100,000 messages per month sustained), bundled plans are available. The combined cost on a mid-market team sending 20,000 to 50,000 messages per month typically runs 30 to 50 percent lower than the equivalent Twilio-plus-HubSpot stack because the integration overhead and per-user license drops to zero. We publish the full pricing model openly for comparison math.

How does inbound SMS routing work when a prospect replies?

Inbound SMS routes by priority rules: first, caller ID matched to an account owner (the rep assigned to the account receives the reply); second, skills-based routing (match inbound-intent keywords to specialized teams); third, round-robin fallback within the appropriate team. The routing is admin-configurable and composes with team-hour schedules so after-hours inbound routes to the on-call team or an auto-responder. The reply threads to the original conversation on the contact record so the rep sees the full exchange chronologically. For teams running a shared SMS inbox pattern (any available rep can pick up the next inbound), the admin configures the pool and the rotation.

Can we send transactional SMS like two-factor codes alongside marketing SMS?

Yes with campaign separation. Transactional SMS (two-factor codes, account alerts, order confirmations, appointment reminders) and marketing SMS (promotional offers, newsletter content) register as separate 10DLC campaigns with different throughput tiers and different consent requirements. Transactional campaigns typically approve faster because the use case is clearly transactional; marketing campaigns face stricter vetting. The admin configures which rep groups or Flows can send to which campaigns. The pattern avoids the common mistake of running transactional and marketing on the same campaign, which both constrains transactional throughput and raises carrier-filtering risk on the marketing side.

How does Strkr compliance posture work for HIPAA-regulated SMS and international markets?

Strkr is HIPAA compliant with a Business Associate Agreement available for teams sending SMS containing protected health information (appointment reminders, lab-result notifications, prescription refills in healthcare SaaS). The posture includes encrypted message storage, role-based access to conversation history, audit logging, and configurable retention per record type. For international SMS (UK, EU, Canada, Australia, Latin America), carrier-level routing uses the local in-country sender when available and respects the local regulatory frameworks (PECR in the UK, GDPR consent requirements in the EU, CASL in Canada, APP in Australia). Opt-in capture tracks the jurisdiction so cross-border sends respect the local rules automatically. For high-regulation markets (specific EU member states with stricter rules, Switzerland, Singapore), the admin can configure per-market rules. The combined posture satisfies the common regulated-industry procurement review and has passed audits with several healthcare and financial-services customers running international motion.
