FAQ
Can you fix Mailgun API errors?
Yes. I can investigate API authentication, configuration and sending errors and fix the underlying issue.
Can you fix Mailgun SMTP problems?
Yes. I can troubleshoot SMTP credentials, configuration and connection issues.
Can you verify my Mailgun domain?
Yes. I can help configure the required DNS records and complete the domain verification process. Mailgun's current documentation specifically uses DNS records for domain verification, including SPF, DKIM and related records.
Can you fix Mailgun webhooks?
Yes. I can configure and troubleshoot webhook endpoints and event handling. Mailgun currently supports events such as accepted, delivered, temporary failure, permanent failure, unsubscribed and complained.
Can you fix emails going to spam?
I can inspect the technical sending setup, domain authentication and delivery configuration and identify issues that may contribute to poor delivery. I do not guarantee inbox placement.
Do you work with existing Mailgun integrations?
Yes. I can troubleshoot an existing setup instead of requiring you to rebuild everything.
