Custom Receiving Domains

To receive emails at your own domain (e.g. reply@updates.yourcompany.com or inbound@yourdomain.com), configure an inbound MX record at your DNS provider.

Dedicated Inbound Subdomain (Recommended)

If your root apex domain (yourcompany.com) already uses Google Workspace, Microsoft 365, or Fastmail for employee mailboxes, do not change the apex MX records. Instead, configure a dedicated inbound subdomain such as:

inbound.yourcompany.com
reply.yourcompany.com
support.yourcompany.com

This ensures your team’s regular business inboxes continue functioning without disruption.

Required DNS Records for Inbound

Add the following records at your DNS host:

Type	Name / Host	Priority	Value / Target
`MX`	`inbound.yourcompany.com`	`10`	`inbound-smtp.us-east-1.amazonses.com`
`TXT`	`inbound.yourcompany.com`	-	`v=spf1 include:amazonses.com ~all`

Verifying Inbound Route

Once DNS records are active:

In the Mailofly dashboard, open Domains → select your domain.
Toggle on Inbound Routing.
Mailofly will verify the inbound MX record and enable the inbound webhook listener.
