Real placement tests
See whether your messages actually land in the inbox, Promotions, or spam across major mailbox providers — measured, not guessed.
Continuous email deliverability monitoring
Spam folders are silent.Your deliverability monitoring shouldn't be.
Swift Mail Ops continuously tests where your email actually lands — inbox, Promotions, or spam — across every mailbox you send from. Connect Google Workspace or Microsoft 365 in minutes and catch deliverability drops the day they happen, not weeks later in your reply rate.

The problem
Deliverability doesn't fail loudly. It drifts.
Placement erodes quietly — a blacklist here, a DNS change there, a provider quietly rerouting you to spam. By the time your reply rate flags it, you've been sending into the void for weeks and the domain damage is done.
A one-off spam test is a snapshot. Swift Mail Ops is a camera that never stops rolling — so the drop on the right gets caught at week five, not at the end of the quarter.

Day 1Day 90
Scheduled checks on every mailbox, every day. Drops surface the day they happen — with an incident and an alert.
Core features
Everything that decides where your email lands, in one place.
Mailbox, placement, domain, and verification signals together — so you can spot problems early and investigate them with clear historical evidence instead of guesswork.
Always-on inbox monitoring
Every connected mailbox is checked on a schedule. Health, delivery signals, and the quiet changes that hurt performance — recorded over time.
Domain health, explained
SPF, DKIM, DMARC, DNS, and blacklists tracked continuously — with the reason a check failed spelled out, not just a red X.
Scores, incidents, alerts
Every mailbox and domain gets a health score with history. When something drops, an incident is recorded and you hear about it.
Email verification
Verify addresses before a bad list drags down the reputation of every mailbox you send from.
Google Workspace & Microsoft 365
Connect business mailboxes with provider-managed OAuth. No shared passwords — revoke access anytime from your provider.
How it works
Connect once. Monitored forever.
01
Connect in minutes
Authorize a Google Workspace or Microsoft 365 mailbox with OAuth. Swift Mail Ops never sees your password, and you can revoke access at any time.
02
We monitor around the clock
Placement, inbox, domain, and reputation checks run automatically on every connected mailbox. There is no test to remember to run.
03
Act before it costs you
Health scores, trends, and incidents show exactly what changed, when it changed, and which mailboxes need attention first.
Google account access
Why Swift Mail Ops requests access to your Google account
Google account access is used only to securely connect your mailbox so Swift Mail Ops can monitor inbox health, email placement, deliverability, and mailbox performance.
The application does not read or use email content for advertising or unrelated purposes. Access is limited to the permissions needed to provide the mailbox monitoring and deliverability features you choose to use.
OAuth lets you approve access directly with Google without giving Swift Mail Ops your Google password. You can revoke access from your Google account or disconnect the mailbox from Swift Mail Ops at any time.
Built for
Teams whose pipeline depends on the inbox.
Swift Mail Ops is built for organizations that send business email at volume and need an ongoing, understandable view of deliverability — not a one-time test.
