Built-in authenticated SMTP

Reply from your inbox.
Send as your domain.

Connect MailerZ SMTP once, then answer incoming email or start a new message from Gmail, Outlook, an email client, website, or approved application.

Gmail compatible Outlook compatible SMTP credentials included Verified senders only

Send without another provider

One setup for replies, new mail, and applications.

Use the same sending service across your daily inbox, email clients, contact forms, and approved product workflows.

Gmail and Outlook

Add your domain address as a sending identity and keep working from the inbox your team already understands.

Multiple verified addresses

Send from support@, billing@, hello@, or another approved identity without creating separate mailbox seats.

Authenticated sending

Credentials are tied to approved domains and identities, preventing open-relay behavior and unauthorized From addresses.

Outbound delivery records

Track sending activity and delivery responses beside the inbound forwarding history for the same domain.

Consistent visible identity

Recipients see your professional domain in the visible From field, not Gmail, MailerZ, or a forwarding address.

Websites and approved apps

Use standard authenticated SMTP for forms, notifications, clients, and applications that support it.

Connect once

A clean reply-and-send workflow.

No separate SES, Mailgun, Postmark, or self-hosted server is required for the standard sending path.
