SMS API: navigating global compliance in 2026

A practical guide to TCPA, GDPR, and carrier compliance across the markets that matter most.

Global SMS means global rules. Consent, sender registration, and opt-out handling vary by country and carrier, and getting them wrong risks blocked traffic and penalties.

Collect and record consent, register sender IDs and short codes where required, and always honour opt-outs. In the US that means TCPA and 10DLC; in the EU, GDPR.

Delark handles sender registration and opt-out processing for you, so you can focus on the message rather than the paperwork.
