Getting started

Create your account, verify the domain and connect your application. Finish with a test email and check its outcome.

Before you start

You need access to your domain’s DNS and an email address to confirm your account. The panel requires a plan and a payment method to create credentials and send.

Order

To the first email

Follow these steps in the panel. Each link takes you to the settings or guide you need.

  1. Account and confirmed email

    Sign up and confirm the email link. You cannot send without this.

    Go to Create account

  2. Add the sending domain

    On Domains, Add domain. Use the domain that will appear as the sender (for example example.com), with no https or paths.

  3. Publish what each card asks for

    The domain page shows DKIM, SPF and DMARC records. Copy the type, name and value of every record. Use the name format required by your DNS provider and check the full name after saving.

  4. Verify the domain

    When you have saved the records, press Check now. If it stays pending, check the name, the type on each card, and that DNS has had time to update.

  5. Contract a tier and save a card

    In Billing, pick a tier. Under Payment methods, save a card. Review the amount and terms shown in the panel before confirming your subscription. The panel will not create keys or send a test until both are in place.

  6. Choose how you will send

    On the domain page, under Connection: SMTP username and password, or an API key starting with ms_…. If you use MCP, the same key works.

  7. Send a test

    Send a test from the verified domain. Check status and errors in Statistics, then check the recipient mailbox. The panel will not send without a tier and a card.
