Mailgun FAQ

Frequently asked about Mailgun

Can I self-host Mailgun or is it strictly a cloud service?

Mailgun is a fully managed cloud-based email delivery service and does not offer a self-hosted version. All email sending, deliverability monitoring, and validation features run on Mailgun's infrastructure, so you cannot deploy it on-premises or offline.

Community insight informed by Reddit discussions

Does Mailgun provide offline email sending capabilities or queueing if my app loses internet connection?

Mailgun requires an active internet connection to send emails via its API or SMTP. It does not provide offline queueing or local email sending features. You must implement your own local queueing mechanism if you want to handle intermittent connectivity before forwarding emails to Mailgun.

Community insight informed by Hacker News discussions

Who owns the email data and logs when using Mailgun? Can I export or delete all stored data?

Mailgun retains email sending logs and analytics data as part of their service. While you retain ownership of your email content, Mailgun stores metadata and logs on their servers. You can export logs via their API for a limited retention period and request data deletion per their privacy policy, but full raw data export is limited.

Community insight informed by StackOverflow discussions

Are there any API limitations or rate limits I should be aware of when using Mailgun for high-volume sending?

Mailgun enforces rate limits and API usage quotas depending on your plan. Free and lower-tier plans have stricter limits on the number of messages sent per month and API request rates. Higher-tier and enterprise plans offer increased limits and dedicated IPs to support high-volume sending. It's important to review your plan's limits to avoid throttling.

Community insight informed by Forums discussions

What is the recommended process to migrate from another email service to Mailgun without losing deliverability history?

Migrating to Mailgun involves updating your DNS records (SPF, DKIM, DMARC) to authorize Mailgun sending, importing your contact lists, and gradually shifting sending volume to Mailgun. Deliverability history from your previous provider is not transferable, so you should monitor reputation closely and warm up your IPs if using dedicated IPs. Mailgun provides tools to monitor inbox placement to help during migration.
