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…”
