Why is my test email landing in spam but production emails don’t?

Hello I’m seeing something confusing and wanted to ask something from the community.

Whenever I send test emails from Mumara, they often land in Spam (especially Gmail). But when I send the actual campaign to my real list, inbox placement looks fine.

Same server, same domain, same template yet totally different behavior. Is this normal? Or am I missing something obvious?

Any help in this matter would be very helpful.
 
Yep this is actually very common, and in most cases it’s not a Mumara bug at all.

Test emails don’t behave like real campaigns. When you send a test email, you’re usually sending it to:
  • Your own inbox
  • A brand-new or isolated address
  • An address with no prior engagement history
Mailbox providers (Gmail, Outlook, etc.) rely heavily on engagement signals. A single test email with no opens, no replies, no clicks looks suspicious so spam filtering becomes aggressive and test emails often bypass “campaign context.”
 
That actually makes a lot of sense. I was judging deliverability purely on test emails

Good to know this is expected behavior. Thanks for the detailed breakdown!
 
Test emails are only good for design, personalization, and to check the working not deliverability judgment.

Test sends don’t fully reflect:
  • Throttling behavior
  • Volume ramp-up
  • Natural sending patterns
Mailbox providers trust consistent campaign traffic more than isolated tests.
 
Here are some simple rules:
  • Use test emails only for preview & QA
  • Check deliverability using real campaigns
  • Send tests to multiple inboxes (Gmail, Outlook, Yahoo)
  • Open or click test emails occasionally
  • Ensure SPF, DKIM, and tracking domains are properly set
If production emails are landing fine you’re good to go.
