Verify your from address and use a custom domain

The From Address is the address recipients see at the top of an email in their inbox. Maxemail authenticates your use of this domain with DKIM (DomainKeys Identified Mail).

📘
DNS records
Add the required DNS records through your DNS provider. Ask your DNS administrator, IT team, web-hosting provider, or other DNS provider administrator to make these changes.

Add the following new DNS configuration for your domain and then let the Maxemail Support Team know:

Record name	Record type	Record value
`maxemail._domainkey`	CNAME	`dkim.mxmfb.com`

This record for Maxemail does not conflict with any other domain settings or providers. DKIM authentication proves to mailbox providers that the sender can use the From Address and adds a digital signature to each message. This also proves that the email content has not been changed in transit.

Custom subdomain

Emails have a send domain that identifies the sender. In personal emails, this often matches the From Address. As a bulk email system, Maxemail must identify itself through the send domain.

📘
Send domain
The send domain is also called the sender, return-path, mail-from, or envelope-from. These terms refer to the original sender of a message and the address that receives bounces.

By default, Maxemail uses mxm.mxmfb.com as the send domain and link-tracking domain.

For improved deliverability, the From Address and Sender Address should be aligned. Alignment means that they use the same domain or a subdomain variation.

Choose a new subdomain, such as email , news , or click. The subdomain must not have been used previously.

Add the following DNS record for the chosen subdomain:

Record name	Record type	Record value
`email` (or chosen alternative)	CNAME	`mxm.mxmfb.com`

Only one custom domain can be configured per customer space. Maxemail also uses this domain for tracking links so they match your brand. Contact the Maxemail Support Team after you add the DNS record so they can complete the custom domain configuration.

Examples

Before adding the custom domain, the sender is not aligned:

Email header showing unaligned From Address and sender domains — Unaligned domains

Using a subdomain as the custom domain gives alignment:

Email header showing aligned From Address and sender domains — Aligned domains

SPF

Maxemail does not require a separate SPF configuration. SPF stands for Sender Policy Framework. Maxemail is the sender and maintains the required SPF records.

Domain email server blocking

Your business email server may block messages that use its From Address but arrive from an external sender. This can prevent you from receiving your own Maxemail messages, even after you configure authentication.

Allow Maxemail sending IPs on the email server for your corporate domain. This is a configuration setting on the email server. Add this IP range to its allowlist: 109.68.64.0/21.

Google Workspace

To set the IP in Google Workspace, in the Admin Console navigate to Apps > Google Workspace > Gmail > Spam, phishing and malware > Email allowlist. For more information please see this Google Workspace help article.

Resellers

If you are a Maxemail reseller, follow the same requirements for your clients, using the reseller-specific DNS domains. See Reseller setup.
