The shipped workflow

This is the feature path BTST supplies—not a claim that your app needs no integration work.

  1. Connect delivery

    Configure a Resend, Mailgun, or custom email adapter and the public URL used by email links.

  2. Build an audience

    Collect or import subscribers and organize recipients with tags.

  3. Prepare a campaign

    Write Markdown or HTML, send a test, and choose the intended audience.

  4. Send and review

    Send immediately or dispatch scheduled campaigns through your server job, then inspect engagement records.
