Pros

“They provide backward compatibility with their old API to reduce downtime during upgrades, especially for legacy systems where upgrading to the latest library or source code is not feasible.”

Alan P.

Software Engineer

“Steep Learning Curve: The sheer breadth of options (dedicated IPs, suppression lists, custom routing) can overwhelm newcomers; the UI feels more like a developer console than a user‑friendly dashboard.”

Gilbert P.

DevOPS

“Limited Built‑in Email Templates: Unlike some competitors, Mailgun doesn’t offer a visual template editor; you need to craft HTML yourself or use third‑party tools.”

Gilbert P.

DevOPS

Pros

“It has replaced our other tools as the go to for email campaigns, sign-up form builder, welcome automations and cart abandonment automations.”

James P.

Marketing Specialist

“My main concern is segmentation, it's great for ecommerce stores, but it would also need more simplistic approach for businesses that push their monthly newsletters to pretty much same contact lists.”

Arnas S.

Marketing Specialist

“It saves a lot of time compared to sending emails manually, and I can see real improvements in repeat sales and engagement.”

Aleksandar I.

Creative Director

Cons

“Pricing Complexity: While free tier is generous for low volume, the cost structure (per‑sent + per‑recipient, dedicated IP fees, and extra features) quickly adds up, making it hard to predict expenses without careful budgeting.”

Gilbert P.

DevOPS

“Need your own custom domain which is understandable for the sake of potential email spam which degrades the credibility of the platform.”

Edward L.

Manager

“I didn't like how mailgun disable our account (with over 25 active applications/domains and hundreds of users) and didn't tell use why for over 3 days.”

Niels v.

CEO

Cons

“The cost for the service can become quite high once your subscriber list gets over the 50k mark, so it may be less appealing to larger businesses.”
