The recipient variables help us to personalize these emails for thousands of customers.

Guest Management System


We used to use WordPress SMTP plugins to increase deliverability for the emails sent from our clients’ WordPress websites. These were very error-prone because there were still some deliverability issues and the emails would break every time the client changed their email password as they would forget to to change it on the website. Mailgun is easier to set up, more reliable and doesn’t require customer passwords – a much better solution!

All email sent via UserVoice goes through Mailgun. Mailgun also handles incoming email for our ticket system. Handling incoming email is where Mailgun really shines. In particular: All emails are converted to UTF-8; There’s always a ‘plain’ (text only) version of the email sent to us, even if the original email only included HTML; They offer a ‘stripped-text’ field, which lets us easily see the new part of an email thread. Also, pretty great support.


UserVoice creates simple customer engagement tools that help companies understand and interact with their customers and build customer relationships that last.


We’ve been pleased with our Mailgun experience. During implementation the Mailgun team was responsive 24/7 to our engineers as they integrated our systems. Mailgun also took our feedback and quickly improved support for our specific sending patterns. The seamless implementation of new domains has eased the workload on our engineering team and allows me to expedite our team’s work. Finally, I love that we can easily verify our logs against what Mailgun is tracking via their website or APIs.

Causes Sees 20% Increase in Clicks with Mailgun

Mailgun is our primary provider for email. We use Mailgun because it concentrates on transactional emails (of the sort that we send) rather than other mail services which are more geared towards bulk mailings. Other services end up sending massive amounts of emails for large mailing lists which causes periods of slow delivery. We are very vested in timely delivery, whereas most other services are concerned about not being blocked as spam. Mailgun is consistently fast.
