Configure your sending domain so your emails arrive

Updated 2026-07-13

In two lines: before your first send, you configure your sending domain in Settings > Branding, Email Domain tab. That way the emails go out from your brand (not from a generic address) and have far more chances of reaching the inbox instead of spam.

Why do I need to configure a domain?

Email providers trust a verified domain more. Configuring it gives you three things:

  • Your brand — the emails go out from yourdomain.com, not from a system address.
  • Better delivery — a verified domain reaches the primary inbox more often and lands in spam less.
  • Enabling sends — without a configured domain, MB Suite blocks campaigns to protect your reputation.

How do I configure it?

Go to Settings > Branding, Email Domain tab, and follow the wizard to connect and verify your domain. It's a guided step you do just once.

Once verified, that domain feeds your Senders: the address each campaign goes out from. The first sender you add stays as the default.

If your account belongs to an agency, you may already inherit its verified domain and not need to configure your own. If you send with your own brand, verifying your domain is the step you can't skip: without it, sends stay blocked.

What is the postal address it asks me for?

Bulk sends must include a physical postal address of the sender: it's a legal requirement (CAN-SPAM) that also improves trust and delivery. You add it in that same Email Domain tab. Without it, MB Suite won't let you send.

Sending emails and its acceptable use (consent, anti-spam, and content policies) are governed by the Terms and Conditions, which always hold the current version.
