What Are formstack.com's MX Records?

MX records for formstack.com specify which mail servers are responsible for accepting email messages sent to @formstack.com addresses. Each MX record contains a priority number and a mail server hostname. The priority determines which server is tried first: lower numbers indicate higher priority.

When you send an email to someone at formstack.com, your mail server performs a DNS lookup for formstack.com's MX records. It then attempts delivery to the highest-priority (lowest-numbered) server first. If that server is unavailable, it falls back to servers with higher priority numbers, ensuring reliable email delivery for formstack.com.

Examining formstack.com's MX records reveals which email provider handles mail for the domain. This is useful for verifying email configuration, troubleshooting delivery issues, or simply understanding formstack.com's email infrastructure.

How MX Priority Works

MX priority values determine the order in which mail servers are contacted. A domain with MX records at priority 10 and 20 will receive mail at the priority-10 server first. If that server is down or unreachable, the sending server automatically falls back to the priority-20 server.

Multiple MX records with the same priority value enable round-robin load balancing, distributing email traffic evenly across several servers. This is common with large email providers like Google Workspace and Microsoft 365, which use multiple servers at the same priority level to handle high volumes of mail.

If formstack.com has multiple MX records, the priority values indicate which server is the primary mail handler and which ones serve as backups. A well-configured domain should have at least two MX records at different priorities for redundancy.
