Early access: send from your own mailbox today. What works

See where your email lands, and why.

Inboxed tests where your email lands, reads your DMARC reports and Gmail’s spam rate for you, checks DNS and blocklists on a schedule, and builds every campaign email the way Gmail and Yahoo ask bulk senders to.

An example placement test: one email to seed inboxes at several providers, with the Gmail tab it landed in. Beside it, the checks Inboxed runs on a schedule.

What it does

  • Inbox placement tests

    Send one email to a set of seed inboxes at Gmail, Outlook, Yahoo, iCloud, Zoho and others, and see inbox, spam or missing for each. Free, 5 tests a day.

  • Gmail tabs

    On Gmail seeds, see whether you landed in Primary, Promotions, Social, Updates or Forums.

  • DMARC monitoring

    Aggregate reports for your domains are read for you: sources by IP, pass and fail per day, and an alert when failures spike.

  • Gmail spam rate

    Connect Google Postmaster Tools and see each domain’s spam rate daily, with a warning at 0.1% and an alert at 0.3%.

  • DNS checks

    SPF, DKIM, DMARC and MX checked daily for every mailbox’s domain, with the exact record to add.

  • Blocklist watch

    Sending domains are checked every 6 hours; a listed domain pauses its mailboxes and tells you.

  • One-click unsubscribe

    Every campaign email carries List-Unsubscribe and List-Unsubscribe-Post headers, so Gmail and Yahoo show their own unsubscribe button.

  • Feedback-ID

    A Gmail Feedback-ID header per campaign, so Postmaster Tools can report spam complaints per campaign.

  • CAN-SPAM footer

    Your company name, postal address and an unsubscribe link in every campaign email. Launches are blocked until they’re set.

How it works in Inboxed

  1. Check the domain

    Run the free checkers below, or connect a mailbox and Inboxed checks it daily.

  2. Point DMARC reports at Inboxed

    Add the rua address we give you (domains bought here get it automatically).

  3. Connect Postmaster Tools

    Sign in with Google once; Inboxed pulls the last days for each verified domain daily.

  4. Test before a big send

    Run a placement test from the mailbox you’ll use, with the email you’ll send.

Honest limits

What this doesn’t do, and what it needs from you.

  • Placement tests use a small set of seed inboxes. They show a pattern, not what every recipient’s filter will do.
  • Gmail tabs can only be read when the seed’s server offers Gmail’s search extension; otherwise any tab counts as inbox.
  • Postmaster Tools only reports domains you have verified with Google, and only once Gmail sees enough volume.
  • The free blacklist checker only queries lists whose terms allow a free commercial tool. Spamhaus, SURBL and URIBL don’t, so check those on their own sites.

Questions

What do Gmail and Yahoo require from bulk senders?

For senders of more than 5,000 messages a day to Gmail: SPF and DKIM, a DMARC record (p=none is allowed), one-click unsubscribe with a visible link, and a spam rate under 0.30% in Postmaster Tools (ideally under 0.10%). Inboxed builds campaign emails to meet the parts it controls.

What does the CAN-SPAM footer need?

A valid postal address (a street address, a registered PO box or a private mailbox), and an opt-out that is honoured within 10 business days. Inboxed unsubscribes people at once.

Are placement tests charged?

No. They’re free, up to 5 per workspace in 24 hours.

Why don’t you check Spamhaus in the free tool?

Spamhaus’s free public mirrors are for non-commercial use; commercial tools need a paid data feed. We only query lists whose published terms allow our use.
