What is business SMS, and how is it different from personal texting?
Business SMS, often called application-to-person or A2P messaging, is any text sent from a software platform through a carrier network to a recipient on a mobile device. Unlike a text from a personal phone, business SMS passes through carrier filters that score sender reputation, campaign type, and content against registered intent. Senders need a registered brand, a registered campaign, documented consent, and clean opt-out handling. In exchange they get throughput, delivery receipts, and audit trails that a personal number cannot offer. Strkr Messaging ships every one of those controls on day one.

What is 10DLC, and does my sales team need it?
10DLC is the U.S. carrier framework for sending application-to-person messages over standard ten-digit long codes, administered through The Campaign Registry. Every business that sends A2P SMS to U.S. mobile numbers must register a brand, verify its tax ID and website, and register one or more campaigns describing the use case, sample messages, and opt-in flow. Carriers then assign a trust score that governs throughput and filtering. Skipping 10DLC does not just risk fines; carriers will throttle or block unregistered traffic within days, which quietly kills a sales cadence before the team notices.

What does TCPA require for sales text messaging?
The Telephone Consumer Protection Act requires prior express written consent before sending a marketing text to a mobile number using automated technology. Valid consent identifies the sender, discloses that automated messages may be sent, states that consent is not a condition of purchase, and shows message frequency and data-rate language. Senders must honor STOP, END, QUIT, UNSUBSCRIBE, and CANCEL replies permanently, respect quiet hours of 8 a.m. to 9 p.m. in the recipient time zone, and screen against the national Do Not Call registry. Settled TCPA cases commonly run five hundred to fifteen hundred dollars per message.

What is the difference between SMS and MMS?
SMS, or Short Message Service, carries up to 160 characters of plain text per segment, with longer messages split into concatenated segments by the carrier network. MMS, or Multimedia Messaging Service, carries images, GIFs, short video, audio, vCards, and up to roughly 1,600 characters in a single message. MMS costs more per send and consumes more carrier capacity, but it lifts response rates on product reveals, order confirmations, and account-based plays. Pick MMS when a visual earns its place; pick SMS for status, confirmations, and short conversational replies. Strkr Messaging bills both at transparent per-segment rates.

What is double opt-in for SMS, and when is it required?
Double opt-in for SMS is a consent pattern where the recipient first provides their number, then confirms by replying YES or clicking a link in a verification text, before any marketing message goes out. Carrier network principles treat double opt-in as a best practice for marketing campaigns, and several high-risk categories such as financial services, debt collection, and age-gated content require it. The second confirmation gives you a second timestamp, a second IP context, and a second piece of evidence that the contact actually meant to opt in, which is the difference most TCPA plaintiffs attack first.

How should we handle STOP and HELP replies?
Every A2P SMS program must honor STOP, END, QUIT, UNSUBSCRIBE, CANCEL, and OPTOUT replies by immediately suppressing the number across every campaign that shares the sender identity, and must respond to HELP with a short message naming the brand, listing a support contact, and restating message frequency and rates. Carrier network rules enforce these keywords regardless of what your opt-in copy says, and failures surface fast in brand trust scores and campaign throttling. Strkr Messaging processes keyword replies automatically, writes the suppression to the contact record, and blocks future sends across every cadence.

What drives SMS deliverability, and how do we protect it?
SMS deliverability lives and dies on four signals: a registered 10DLC brand with a strong trust score, campaigns whose live content matches the registered sample messages, consent-sourced recipient lists with low STOP and spam-report rates, and content that avoids filtered terms such as unregistered URL shorteners, prohibited verticals, and all-caps shouting. Carrier networks score traffic in near real time, so one bad send can slash tomorrow throughput. Protect the number by warming it, keeping message volume predictable, rotating long links to a branded domain, and segmenting marketing from transactional traffic.

When should sales use SMS instead of email?
SMS wins when the message is short, time-sensitive, and expected: meeting confirmations, follow-ups after a demo, contract reminders, event reveals, and one-to-one replies inside an active conversation. Email wins when the content is long, needs rich formatting, or has to carry attachments, dashboards, or legal copy. The honest rule is that SMS buys attention the recipient has already granted, while email is where you earn attention through content. The strongest cadences pair the two, with SMS used sparingly to nudge an email thread forward rather than to replace it.
What are the quiet hours and frequency limits for sales SMS?
TCPA and carrier network principles converge on quiet hours between 9 p.m. and 8 a.m. in the recipient local time, meaning your platform must know every contact time zone before scheduling a send. Carrier guidance also treats sustained send volumes above a few messages per contact per week as a red flag for marketing campaigns, with conversational and transactional traffic enjoying higher ceilings. Frequency, time of day, and content type all feed into the trust score that governs tomorrow throughput, so a conservative pace plus honest disclosure in your opt-in beats volume every time.
How are international SMS rules different from U.S. rules?
Outside the United States, SMS rides different consent regimes and different carrier frameworks. The United Kingdom and the EU treat marketing SMS as electronic communication under GDPR and the ePrivacy Directive, so most sends need prior affirmative consent rather than legitimate interest. Canada under CASL requires express or implied consent for nearly every commercial electronic message. Australia enforces the Spam Act 2003, and India requires DLT template registration before a single marketing text leaves the gateway. Route international traffic through a system that tracks jurisdiction, consent basis, and local keyword rules per contact.
What do we need to register a 10DLC brand and campaign?
Brand registration through The Campaign Registry requires the legal entity name, EIN or tax ID, country of registration, website, business vertical, physical address, and an authorized representative with contact details. Campaign registration adds the use case category, a plain-English description of what you intend to send, two or more sample messages that match live content, your opt-in flow with URL or screenshot, and your opt-out language. Expect brand vetting to take hours to days and campaign review to run from a day to roughly a week. Strkr Messaging automates every step inside the admin surface.
Does Strkr Messaging handle compliance and carrier registration for us?
Strkr Messaging ships the controls a compliant SMS program depends on, including guided 10DLC brand and campaign registration, consent capture tied to each contact, suppression lists that cannot be bypassed, STOP and HELP automation, quiet hours enforced in the recipient local time, and audit logs that show who sent what to whom and under which consent basis. The platform does not replace counsel or decide what your retention tail should look like, and it does not pick your use case category for you. Those calls stay with your legal and RevOps team; Strkr makes the evidence trivial to produce.
