What customers say

“A big value that Nylas has brought us has been removing the ambiguity with the review process. They helped us navigate exactly how we should approach it and had the answers for all the questions we had. To this day, we’ve passed each of our verification steps. Nylas is a great partner and it’s been a huge benefit that we could feel certain that the process was going to go smoothly.”

Monika Abraham Product Operations Manager at Crunchbase

“We were spending most of our time fixing problems rather than improving our product. Nylas removed these email integration problems from the equation. It was a breath of fresh air…”

Stjepan Buljat CTO at Cognism

“We have such a complex platform that we can’t implement every solution on our own, so we look for the best solutions in the market – that’s why we chose Nylas.”

Maksym Dudnyk Product Manager at Upwork

“One of the top three reasons our customers churn was email deliverability. Nylas solved a critical problem for us overnight. We went from close to 0% to nearly 100% deliverability.”

Justin Belobaba CEO at Nowsite

“We have millions of emails sent each week. Nylas frees us up to focus on…delivering new features to our customers and working with our data science team on exciting new projects.”
