Sounds very interesting! And in Gmail, do the emails go to the Inbox or the Promotions tab?

@mykyta_semenov_Β Great question! For transactional emails (OTPs, receipts, alerts) β inbox, almost always. For marketing campaigns, Gmail's tab placement depends on content, engagement history, and sender reputation β no ESP can guarantee Primary tab, and anyone who claims otherwise is overpromising. What we do is give you the best possible foundation β strong authentication, clean reputation, and engagement best practices β to maximize your chances. π
@amar_cpΒ Reply can ;) But itβs not mass outreach, the goal is a bit different.
The transactional + marketing on one platform pitch makes sense until you hit a deliverability issue and can't isolate which stream caused it. How granular is the per-domain reporting?
But for smaller campaigns it definetlly should work.
