The SendGrid for sales—built
with deliverability in mind
OBM Engine is your API layer for sending cold emails at scale—powered by
infrastructure that protects your domain from Day 1.
Why we built OBM Engine
SendGrid, Mailgun, and Resend were made for password resets and receipts—not cold outreach. So when sales teams plug into them, they get flagged, blocked, or banned.
OBM Engine is different. It’s built for sales, designed for deliverability, and protected by MI Shield—our proprietary AI that filters spammy emails before they’re sent.
