Vincent Turner

“I've been through a number of mail services over the last few years and maileroo is a standout for me. Everything about it. The underlying service is great, the architecture is solid and its super reliable and delivery is fast. As well as that the UX for the interface is also really well crafted making it a pleasure to use. Beyond that the service levels are superb, fast and useful. Lastly, the price point is superb. It really is hard to fault Maileroo, I'd give it 6 stars out of 5 if I could”

Rizky Muhammad

“Very pleasant experience with Maileroo. We successfully migrated from Mailjet without any problems. The technical team was very helpful and listened to suggestions and created new features in a relatively short time.”

Aarón B.

“I really like it. It is a new service, so there is always the possibility that as it grows, it might deteriorate over time, but my experience so far has been exceptional. The instructions for adding domains are clear and easy to follow, domain verification after adding the correct DNS records is very fast, the emails are sent promptly, and so far none of them have ended up in spam folders.”

Umar Faruk

“Maileroo offers an appealing email-sending solution for website owners, and I am extremely pleased to collaborate with them. Their platform is user-friendly and the assistance they provide is remarkably prompt and supportive.”

Shaun Smith-Roberts

“What a Joy to work with, I couldn't be more impressed with the services provided by Maileroo.com. From the moment I signed up, the experience was seamless and efficient. The platform is incredibly user-friendly, making it easy for me to manage my emails and campaigns effortlessly.”

Darius (Webmate)

“The support was really fast, and the whole process was very easy to set up. I requested an increase in the 100 emails/hour limit, and within a few minutes, the team had increased it. So far, so good.”

Kris Flynn

“I'm not a techie person or programmer, and this is my first time using an SMTP server. I was having some issues setting up one of my tools with maileroo's SMTP servers. A quick support chat inquiry led me to one of the co-founders who spent about an hour with me to solve my issue. In the end, it was all my own human error. We were able to fix the issue, but the best thing about the whole experience was how patient and pleasant Areeb was. Just a really great experience, especially for someone like me who isn't a developer or IT specialist.”

Larry

“Maileroo is easy to congifure the SMTP relay to send your transactional emails. It works perfectly. The SMTP plugin that you recommended did not work for me, but I had both problem using a free SMTP plugin. Also I was not able to understand how to use the API. I would like to be able to assigns sending limits per each domain. I only purchased I code because there was only 1 Tier listed. I might have stack 2 codes if I new the limits offer with 2 codes.”

piccinato

“Congratulations to the Maileroo team for creating an easy and user-friendly platform. This is a very nice and generous deal. Thank you.”

christina

“I was blown away by the customer support of Maileroo. I signed up for a free tier of their service because I had a client with simple but specific needs and it seemed like a perfect fit. However, since I was new to setting any of this up, the entire process was a learning curve for me.”

Grega

“We were searching for a new SMTP provider, after the one we were using raised the prices for the 3rd time - in 2 years. We Found Maileroo and couldn't be happier. Everything works smoothly, prices are top-notch, and their support is friendly and helpful.”

Ed Ellingham

“We've been using Maileroo for quite a while now and it just works. Great features, and even better support!”

Dahunsi

“AWESOME! I got to know about Maileroo through an online community and I tried it. I have not used any other service for my transactional mail since then.”
