Sample Message Validator
Paste your campaign sample messages and lint them against the rules carriers actually check — length, placeholders, HTTPS-only links, no link shorteners, brand name, opt-out language, and 2–5 distinct samples.
Sample messages are one of the most-scrutinized parts of a 10DLC campaign. Reviewers reject samples that are too short, identical, missing the brand name, or carrying link shorteners or bare HTTP URLs. Paste your samples below — one per line — and this validator flags the same issues a DCA reviewer would.
How it works
Each line is checked for length (20–1024 characters), the presence of [bracketed] template placeholders, bare http:// links (carriers require HTTPS), and link shorteners (bit.ly, tinyurl, t.co, goo.gl, ow.ly) — which are flagged as failures because they hide the destination. Embedded links and phone numbers are noted so you remember to set has_embedded_links / has_embedded_phone to match.
Set-level checks mirror the registry rules: at least one sample must include your brand name, at least one must include opt-out language (STOP / unsubscribe / cancel), and you need 2–5 distinct samples. See the rejection reasons table for the full list. Everything runs in your browser.
