Content Creation

Write messages that work in 160 characters

Character limits enforced in the editor, not discovered after send.

160-character enforcement

Live character and segment counter flags copy that exceeds one segment during writing.

Auto-concatenation

Longer messages split and concatenated automatically; carriers display them as one on most devices.

Personalization in body

Use {{first_name}}, {{offer_code}}, or any profile field with fallback values.

Compliance

Compliance enforced on every single send

TCPA opt-out and STOP/HELP handling are automatic, not manual processes.

Opt-out list enforcement

Users who replied STOP are permanently excluded from every subsequent send.

STOP / HELP auto-handling

STOP triggers immediate opt-out; HELP returns your configured business name and opt-out instructions.

TCPA compliance

Every recipient must have a valid SMS opt-in. Users without one are excluded before send.

Journeys

Put SMS where it drives the most action

SMS performs best for urgency, use it at the right step, not the first one.

Journey integration

Place SMS as a high-urgency follow-up after email and push go unanswered.

Event-triggered sends

Trigger on a specific user action: offer expiry, appointment reminder, milestone.

Scheduled sends

With quiet hours, deliver based on user timezone; avoid inconvenient delivery times.

“Before Sortment, one campaign took most of a week. With Content AI, we brief it, get copy, variants, and QA in hours, then push. We went from eight campaigns a month to over thirty.”

FAQs

How is TCPA compliance handled?

Sortment enforces opt-out on every send and handles STOP/HELP automatically. Consent collection must be managed at your acquisition touchpoints — Sortment stores and enforces the list from there.

What happens when a user replies STOP?

They are immediately added to the opt-out list and excluded from all future SMS sends, permanently, unless they explicitly re-opt in.

Can I send messages longer than 160 characters?

Yes. Sortment auto-concatenates longer messages into multiple segments. Most devices display the full message as one; each segment is billed separately by your carrier.

Do I need to collect opt-ins myself?

Yes. Sortment enforces opt-out compliance but does not collect opt-ins. Your sign-up flows, checkout pages, or preference centers are where users consent to SMS.

Can SMS be a fallback step in a journey?

Yes. Email on Day 0, push on Day 3, SMS on Day 5 if no action — managed as a single journey in Sortment.
