Sending protections and verification
The one-time verifications required before your first newsletter, the Free-plan warm-up limit, and why sending can pause automatically.

Before your first send
Verify your sending domain Under Workspace → Domains, add the domain you send from. You’ll get a checklist of 4 required DNS records to add at your domain provider (GoDaddy, Namecheap, Cloudflare, and similar); use the copy buttons so nothing gets mistyped, then select Check DNS records. Changes usually appear within minutes but can take up to 48 hours. A fifth record, DMARC, is recommended but optional; it never blocks verification. Once verified, set a default From address on that domain under Workspace → Communications. Mail authenticated with your own domain lands in inboxes; unauthenticated mail lands in spam. Verify a mobile number (Free plan) Under Workspace → Communications → Sending phone verification, enter a mobile number and confirm the 6-digit SMS code. One number per workspace, one time.
The Free-plan warm-up
Automatic pauses
If a send’s hard-bounce rate passes 5%, sending is paused automatically — a bounce rate that high almost always means the list contains addresses that never opted in. Even a send already in progress stops. If a send’s spam-complaint rate passes 1%, the account is suspended pending a human review.
