InboxWatch · by Worksub

In development

Know the morning your emails start landing in spam.

InboxWatch will send scheduled test emails from your key senders to seed inboxes across Gmail, Outlook and other providers. It will check whether each one landed in the inbox, promotions or spam, and alert you in Slack as soon as placement drops. You find out before your reply rates tell you.

No newsletter. We never share your address.

For cold email agencies and ecommerce brands. From Worksub, the team behind CertPilot and EstoppelPilot.

The problem

You find out about spam from the results.

Deliverability breaks quietly. A domain gets flagged, a sending pattern trips a filter, and the first sign is a campaign that gets no replies or a sale that doesn’t sell.

Checking placement by hand means test accounts at every provider and someone remembering to look.

  • Silent failure

    Emails don’t bounce when they go to spam. They just disappear.

  • Many senders, many domains

    Agencies run dozens of mailboxes. Checking each one by hand doesn’t scale.

  • Too late to fix

    By the time reply rates drop, the campaign has already gone out.

How it will work

What InboxWatch is planned to do

This is the plan, not a shipped product. The waitlist decides what gets built first, and what you tell us shapes it.
  1. 1

    Add your senders

    Connect the mailboxes and domains you care about most.

  2. 2

    Tests run on schedule

    InboxWatch will send test messages to seed inboxes at Gmail, Outlook and other providers.

  3. 3

    Placement is recorded

    Inbox, promotions or spam, per provider, per sender, over time.

  4. 4

    You get alerted

    When placement drops, you get a Slack or email alert with the sender and provider affected.

FAQ

Questions about InboxWatch

How is this different from GlockApps or Mailreach?

Honestly, they cover a lot of this already. InboxWatch only makes sense if it does one thing better for you, so tell us in the form what’s missing from what you use.

Will it send from my real mailboxes?

Yes. Placement depends on the actual sender, so tests are sent from the mailboxes you connect, at a low volume you set.

Does this exist yet?

Not yet. It’s in development, and teams on the waitlist get access first. Interest from teams like yours determines what we build next.

What happens when I sign up?

Your email goes on the list for this product, and nothing else. We’ll write when there’s something to try, and we might ask you a question or two about how you work today. No newsletter, and we never share your address.

Want InboxWatch built?

Join the waitlist for early access. We’ll reach out when it’s ready for its first teams.
