Teams that switched, never looked back
From compliance-heavy enterprises to fast-moving startups — read what operators say after moving their people to Qestel.
“We migrated 1,200 seats off a legacy provider in a single afternoon. Qestel handled every domain record, every alias, every forward — our team didn't notice a thing.”
Dana Whitfield
VP of IT, Veltris Cloud
“The reason we switched was privacy, plain and simple. Encrypted at rest, no ads, no scanning, and a real person answers support in minutes. It's how email should have been done from the start.”
Marcus Lee
COO, Merivon Capital
“Their team is white-glove from the first call. Domains, DKIM, SPF, migration — all handled. Our employees got their new mailboxes before lunch. I've never seen onboarding like it.”
