Integrations

Bring any inbox. Connect in two minutes.

Native OAuth for the providers your team actually uses, and standards-compliant SMTP + IMAP for the long tail. Reputation is bucketed per ESP so your scores stay meaningful.

Native providers

One-click OAuth into the big two.

Push subscriptions, scoped tokens, automatic refresh. You authorise once and we keep the connection healthy in the background.

W
Google Workspace
Workspace mailboxes via per-user OAuth consent.
M
Microsoft 365
Microsoft Graph with push subscriptions for real-time delivery events.
SMTP + IMAP

Standards-compliant for the long tail.

Anything that speaks SMTP works. Optional IMAP for reply detection + folder moves — strongly recommended for full warmup signal.

Z
Zoho Mail
App password + SMTP/IMAP. Auto-detected from MX records.
P
cPanel + Plesk
Hosted mail on any cPanel or Plesk box.
ESP coverage

Every recipient bucketed by ESP family.

We group inboxes into Google, Microsoft and Other so a dip in one filter never hides behind a healthy average. The placement check is a Beta feature we're rolling out gradually.

Google
G
Gmail
Inbox / Promotions / Spam placement.

Separate Postmaster Tools signal.
