Warm-up

Inbox placement tests

See where your email lands at each provider: inbox, promotions or spam.

A placement test sends one email from your mailbox to mailzy's own test inboxes at Gmail and other providers, then shows where it landed at each (inbox, promotions, spam or not received), and what each provider made of your SPF, DKIM and DMARC.

How many you get

  • Free and trial accounts: 2 tests in all.
  • Paid plans: 30 a week, plus a free weekly test on every mailbox using its latest campaign email.

A test that reached no inbox at all (every send failed) doesn't count.

Test a campaign before launch

Test where this lands, in a campaign's Editor or on the launch screen, sends your first email exactly as a lead would get it. If it lands in spam, it lists the likely reasons in plain words, such as the mailbox's health, tracking, links, images or advert-like wording. It's suggested, never required.

A spam result sends a bell note and an email with what to check. Nothing is paused.
