Message Template Linter

Live. Check an SMS, email or letter merge template before a campaign: broken or mixed placeholders, fields your data doesn't have, blank names, unformatted amounts, missing opt-out, link shorteners.

Send a template, the channel and optionally your field list and up to 50 sample rows. You get mixed or unbalanced placeholder syntax, placeholders not in your data (including case mismatches), amounts without a dollar sign, public link shorteners, a missing Reply STOP or unsubscribe line, subject lines that reveal a debt and all-caps text. Each sample row is rendered in memory and flagged for missing or blank fields, "Hi ," greetings, leftover raw tokens and badly formatted amounts or dates. Merge mechanics only; check the wording with electronic-contact-gate or script-review. Nothing is sent or stored.

Price: $0.001 per call after 1,000 free per month.
