When you add a domain to Flowforth, one of the required DNS records is an MX record. If your domain already uses an email provider (like Google Workspace or Microsoft 365), you may be wondering whether this will cause a conflict. In most cases, it won’t — here’s why.

​
What is an MX Record?

An MX (Mail Exchanger) record tells the internet where to deliver incoming email for a domain. Each MX record has a priority value — the lower the number, the higher the priority. For example, if you use Google Workspace, you likely have an MX record like this: 
yourdomain.com     MX    10    alt3.aspmx.l.google.com.
This means email sent to anyone@yourdomain.com gets delivered to Google’s mail servers.

​
Will the Flowforth MX Record Conflict?

No. The MX record Flowforth asks you to add is on a subdomain (e.g., send.yourdomain.com), not your root domain. It looks something like this: 
send.yourdomain.com     MX    10    feedback-smtp.us-east-1.amazonses.com
MX records only affect the specific domain or subdomain they’re associated with. Since send.yourdomain.com and yourdomain.com are separate, the Flowforth MX record has no impact on where your regular email gets delivered. Your existing email (Google Workspace, Microsoft 365, etc.) will continue to work exactly as before.

​
Common Conflicts and How to Solve Them

​
Conflicting Record on the Same Subdomain

If you already have an MX record set for send.yourdomain.com from a different service, you’ll need to remove it before adding the Flowforth MX record. Alternatively, you can use a different subdomain when adding your domain to Flowforth (e.g., mail.yourdomain.com instead of send.yourdomain.com).

​
Conflicting Priority Values

Each MX record on the same domain or subdomain should have a unique priority value. Flowforth uses a priority of 10 by default. If another MX record already uses 10, change the Flowforth record to a different value like 20 or 30.
Priority values range from 0 (highest priority) upward. If a priority value is already taken on the same subdomain, simply pick any unused number.
