From catastrophic deliverability to over 50% open rates

I hired MailSoar to help with email deliverability issues I was having with my domain. I was extremely frustrated because most of my emails to a list I worked very hard to build were suddenly landing in spam. I also wanted to optimize deliverability to a new audience, which they handled brilliantly! Not only are is Pierre and his team absolutely wonderful to work with, but my emails are now getting a 50% + open rate. I learned so much working with them, and I look forward to working with them on future projects. Highly recommend!

One year of support and improved email performance

We came to Mailsoar to help with our deliverability. We were so happy with their work on this, that we have continued to work with them for the past year to monitor our deliverability and to act as trusted consultants for a very important email marketing program. Our email deliverability metrics have drastically improved since starting with Mailsoar. As a result of this email performance and revenue improved drastically.

Key recommendations to improve deliverability, which is essential to our business

We had a free consultation where Joe gave us really good recommendations on many aspects to improve our deliverability. This deliverability issue was very important for us, Momento Solutions, as we are a virtual event platform tool.

MailSoar had a huge impact on our business and I highly recommend them. They helped us grow our open rate from ~10% to almost 50% for our eCommerce store by optimizing our email strategy and implementing various deliverability tactics. We have been using their service for a few months now, and I couldn't be happier with their knowledge, expertise, and great communication.

All our emails were going to spam or not being received. I called in hopes for our emails to not go to anyone's spam anymore. Not only did we solve our problem quickly and efficiently but I also learned a lot from Pierre Pignault on why our problems came about and how we solved them.

We encountered problems with the deliverability of our emails and newsletters to new customers for two to three years. We tried working with several specialists, but the problem was never really solved due to its complexity. This created a lot of stress and even sometimes affected our customers' confidence in our daily work... When I discovered Mailsoar online, I decided to give it one last try. Pierre immediately made himself available to organise a meeting and carry out a series of very precise professional tests. He is the best expert I can recommend in this field. He identified all the ...

We worked together on a Gmail deliverability issue, as a significant portion of our marketing and transactional emails were not reaching the primary inbox (many were ending up in spam or the Promotions tab), which directly impacted our open rates and revenue. We are already seeing a gradual improvement in the open rate on Gmail, a sign that our emails are returning to the main inbox more effectively, even though optimisation is still ongoing.
