We are on a free plan here

We are on a free plan here. Still, Mailgun is doing it's best to help, even if they get nothing in return financially. I dont know what else to say; but I do like and enjoy this service.

Suddenly account closure

Have been using Mailgun for 3 weeks. Everything went well until suddenly i couldn't login anymore. After contacting Support, they told me they decided to permanently disable my account, without giving any reason. I didn't violate any of their AUP. I don't recommend to rely on Mailgun, they will do huge damage to your business

Mailgun burned us

We're a small US-based furniture manufacturer. With no warning or explanation, Mailgun suspended our account and then customer service didn't reply to any emails for 24 hours. We had been using Mailgun for transactional email from various web apps and sites, so the suspension shut down our customer ticketing system, ecommerce, and project management. Garbage service; unpredictable, unreliable, and as a result useless for small enterprises.

Hey Robert, very sorry to hear that this happened. It seems that our application is mission critical for your business, you may want to look into a support plan that includes live phone and chat support for immediate issues like these. Hope you have a great week and thank you for choosing Sinch Mailgun.

ZERO SUPPORT

I think somebody put a mailgun to the heads of these nerds and pulled the trigger. Zero customer service, business acumen or common sense. Our webmaster went MIA (mental breakdown during a divorce) so when we needed to upgrade our account (for a monthly fee) these binary-speaking boneheads could not just take the money and upgrade the account. Instead they demanded we do everything online using login information we cannot retrieve. So instead of actually helping us…they sent us on a long and arduous series of department transfers and email strings going straight to Hades. Whoever the “suit” is running this place has no grasp of the term “customer care” and dismisses those seeking assistance entirely. They could ask me questions about the company that only the owner could provide or email em proof in a number of ways but nooooooo! You must have your API key ID and a bunch of other stuff only a webmaster would have. So frustrating!!! We are losing money hourly because of this and a week of communicating with their “techs” has resulted only in more losses, increases blood pressure and this review! Wasted an entire week on these weaklings! Gunmail is so enveloped in bovine excrement they cannot even see how badly their service is run. I imagine they are all running around playing video games, taking daytime naps on beanbag chairs in their safe spaces and wearing shoes with Velcro laces. The vacuum that is their “support staff” sucks and if this measure of suckage increases, I fear they will create a black hole and drag all of humanity into oblivion. All they had to do was call me, confirm I own the business and take the charge card for monthly payments. Taking the money from eager customers is the #1 priority of any business but these tools cannot grasp that. I know kids operating lemonade stands with more business sense than Gunmail. So if you lack adequate grief in your life…try doing business with Gunmail. They set the customer care bar so low…you need a backhoe to find it. Should relabel the service mailfail.

Fantastic Service

Mailgun has been a great mail service for my small blog. I even had an issue where my blog became compromised by a significant CVE and Mailgun was able to detect misuse of their service by the compromised credentials. They helped me get back on my feet quickly sending mail and I was able to quickly contain the compromised service because of their early altering. Top notch service.

Top-notch support from Sinch Mailgun Support

What great service from Mailgun! I wanted to change my email address, but it turned out that wasn't possible just like that. I've now experienced that they handle this in a very secure way. Luckily, I got help from three wonderful people: Priya, Liam and John P. What struck me most: they were fast, friendly and really thought along with me. No standard replies, just genuine good thinking. From a sunny Netherlands: thank you so much all three!
