What everyone is saying
Trusted by banks, lenders, insurers, and wealth firms.
We replaced two statement printers and a separate certified-mail vendor with MailStream. One contract, one API, one audit log, and tax season ran without a single late notice.
Sarah L.
VP of Operations, Foundry Federal Credit Union
The HITRUST certification and per-piece tracking got us through our SOC 2 audit without a single mail-related finding. The integration took our team a week.
Andre B.
Director of Compliance, Cornerstone Lending
Certified notices used to take a week and three phone calls per batch. Now they go out the same day they are queued, and we get proof of delivery webhooked straight to our case management system.

Operations Lead, Meridian Wealth Advisors
Credit unions, community banks, fintechs, insurers, and RIAs use MailStream to run regulated mail without juggling three vendors or a paper audit trail.
