How it works

Four steps from signup to your first outbound send.

  1. 01

    Create your workspace

    Sign up, name your organization, and land on the overview with credits, health, and onboarding checklist.

  2. 02

    Add domains and inboxes

    Buy or connect DNS zones, then provision Google Workspace or Microsoft 365 mailboxes on those domains.

  3. 03

    Warm your inboxes

    Ramp each inbox over 14 days with API peer mail before full campaign volume.

  4. 04

    Launch campaigns

    Import leads, pick your inbox pool, write the sequence, and send with rotation and telemetry.

Campaigns pause before reputation breaks.

SpringMail tracks bounce rate per campaign, inbox, and domain. Cross the 2% threshold and sending stops automatically, so one bad list cannot burn your domains overnight.
