Guides

Before you send your first campaign

Deliverability comes first, because every workflow depends on messages that actually arrive. Register your brand and campaign for SMS with A2P 10DLC. Set up SPF, DKIM and DMARC on a dedicated sending subdomain, following the sending domain guide. Then warm up that domain for at least four weeks, as the warm-up guide explains.

Two laws matter as well. In the US, the TCPA requires prior express written consent before marketing texts and limits sending hours. With contacts in the EU, GDPR applies: you need consent records, a signed data processing agreement and a process for data subject requests.
