What an SMS marketing platform must do in 2026
10DLC registration, and who files it. US carriers block marketing texts from unregistered local numbers. Your brand and each campaign must be registered with The Campaign Registry before you send. Some platforms file this for you. Others hand you a form and a fee.
Opt-out handling. A reply of STOP, QUIT, END, CANCEL, UNSUBSCRIBE, REVOKE or OPT OUT must remove the contact. Under the FCC's rules, a revocation sent by any reasonable means must be honored within ten business days. The platform should do this automatically, not leave it to a person reading replies. TCPA opt-out rules for business texting covers the detail.
An RCS upgrade path with SMS fallback. RCS shows your verified name and logo, rich cards and buttons in the phone's own messaging app. A platform should be able to send it today, or say when, and fall back to SMS or MMS when a phone cannot take it.
Published rates. You should be able to work out what 10,000 messages cost before a sales call. Look for a per-message or per-credit price, and for how carrier fees are billed.
Consent records. You need to show when and how each contact opted in, for which program, and when they opted out.

How we scored
Every cell uses only what the vendor publishes on its own website, help center or developer docs, checked 7 and 8 October 2026. We did not use review sites, third-party blogs or sales calls. "Not published" means we could not find it on the vendor's own site. It does not mean the vendor lacks it. Prices change, so confirm with the vendor before you sign.

How to choose
Answer these about your own program before you look at any vendor.
- Who will file your 10DLC brand and campaign? If nobody on your team has done it, does the platform file it, and what does it charge?
- What does your monthly volume cost? Multiply your expected segments by the published rate, then add carrier fees. Can you do that sum from the vendor's own page?
- Do you need RCS this year? If yes, can the platform send it today, and does it fall back to SMS on its own?
- How are opt-outs handled? Are STOP replies and plain-language requests applied automatically, across every program you run?
- Can you prove consent? Can you export when and how each contact opted in?
- What are you committing to? Is there a contract, a minimum spend or a setup fee?

Frequently asked questions
What should an SMS marketing platform do in 2026?
It should register your 10DLC brand and campaign, apply opt-outs automatically, send RCS with SMS fallback or say when it will, publish its rates, and keep consent records you can export.
Which SMS marketing platforms support RCS?
On their own sites in October 2026, Attentive, Braze and Klaviyo list RCS as a channel. Postscript runs early access with a waitlist. SlickText offers a verified sender profile. EZ Texting runs an interest form. SimpleTexting, Textedly and Podium do not mention RCS on their pricing pages. SimplyRCS sends RCS with automatic SMS and MMS fallback.
Does RCS cost more than SMS?
It depends on the platform. Some charge setup and annual fees (SlickText publishes $500 once and $200 a year), and some quote it. On SimplyRCS an RCS text segment is $0.0039, the same as an SMS segment, and an RCS media message is $0.0150, plus a one-time $250 RCS Sender ID setup and review.
Can I keep my SMS marketing platform and add RCS separately?
Yes. An RCS platform can run beside your current tool through an API, sending RCS where phones support it and SMS elsewhere. The cost is a second tool and a second place to read results.
Do iPhones receive RCS marketing messages?
Since iOS 18.1, iPhones on supporting US carriers can receive RCS business messages from verified senders. Where a phone or carrier does not support it, the platform should send SMS or MMS instead.
Is RCS marketing subject to the same rules as SMS marketing?
Yes. TCPA consent, opt-out handling and quiet hours apply on every channel, and RCS adds carrier verification of the sender. TCPA compliance for business texting covers the rules, and how RCS consent works the RCS part.
