Quick verdict
SlickText is worth testing for a US or Canada business that wants credit-based SMS marketing, unlimited stored contacts on paid plans, free incoming texts, rollover credits, and a low starting tier. The current monthly range begins at $29 for 500 credits and scales through several published volume tiers. The buyer still needs to model message segments, carrier fees, consent, registration, replies, and optional RCS costs.
Published plans and credit model
SlickText's current monthly tiers list 500 credits for $29, 1,000 for $49, 2,000 for $79, 3,500 for $129, 5,000 for $169, 10,000 for $319, 25,000 for $579, and 50,000 for $939 [SlickText, 2026]. Annual billing is presented with two months free. Verify the live selector before publishing or purchasing.
Paid plans list free incoming texts, unlimited contacts, rollover credits, support, and one premium sending number [SlickText, 2026]. Unlimited contacts should not be confused with unlimited delivery. Credits and any carrier charges still determine how much the program can send.
Estimate volume from campaigns, not contacts
A 500-contact list does not automatically require 500 credits a month. Four broadcasts to that list create a different demand from one appointment reminder sent only to customers with upcoming visits. Long copy, special characters, media, and carrier treatment can also alter the billable message count.
| Input | Budget question |
|---|---|
| Recipients per send | How many consented contacts receive each campaign? |
| Sends per month | Include recurring and seasonal campaigns |
| Message length | Will the copy split into multiple SMS segments? |
| Incoming replies | Who handles responses and exceptions? |
| Carrier charges | What additional per-message charges apply? |
Compliance is an operating process
Software can record an opt-in and process a STOP command, but it cannot decide whether a business had valid permission to send a particular campaign. Save the source, date, disclosure, number, and purpose associated with consent. Separate marketing permission from a phone number collected only to complete an order or appointment.
Test a keyword or form opt-in, the first message, HELP, STOP, resubscription, list import, and an inbound complaint. Confirm that suppressed contacts remain suppressed across future imports. G2 hosts current SlickText customer reviews that can help a buyer identify usability questions, but review sentiment should be treated as a prompt for testing rather than proof of compliance [G2, 2026].
Two-way SMS and RCS fit
Free incoming texts are useful only when someone owns them. Define business hours, response targets, escalation, and what happens when a customer sends sensitive information. Marketing and customer-service replies may need different owners even when they arrive on one number.
SlickText currently lists RCS with a $500 one-time setup fee and $200 annual maintenance fee [SlickText, 2026]. Treat RCS as a separate implementation choice. Ask what devices and campaigns it will reach, what fallback occurs, and whether the added brand presentation changes a measurable outcome.
A controlled trial
Create a small consented test segment. Send one short campaign, one longer message, and one message requiring a reply. Test personalization with blank data, schedule controls, link reporting, STOP, HELP, and an agent response. Record credits used and any carrier line items rather than extrapolating from the plan name.
Before importing the full list, export the test data and suppression record. Verify that another staff member can identify consent source and conversation owner. If the team cannot audit those two facts, the program is not ready for a larger send.
