Sending domains
Add a domain, inspect its DNS requirements, and recheck verification as public records propagate.
Deliverability
Authenticate the sender. Pace the queue. Respect the provider’s answer.
Engage combines sending-domain setup, confirmed sender identities, controlled dispatch, retry handling, and recipient protections without promising inbox placement.
A stronger path to the recipient mail server
Domain authentication establishes who is allowed to send. It supports deliverability, but no platform can guarantee placement or delivery.
SPF, DKIM, and DMARC
Follow focused guidance for sender authorization, message signatures, and visible domain policy.
Cloudflare or manual setup
Use guided Cloudflare setup where available or publish the required records with any DNS provider.
Confirmed sender identities
Control the names, addresses, and reply-to details a message is allowed to use.
Paced background sending
Release recipients individually at an audience-defined speed instead of handing a bulk list to an app-server mailer.
Known Deliverability Protection
Stop or suppress recipients when current permission, complaint, bounce, or other known conditions make sending unsafe.
Authenticated sending
Identity and infrastructure work together

Provider acceptance is not confirmed delivery
Engage keeps those states separate and records later delivery, delay, bounce, complaint, and failure events when they arrive.
