Why ads aren't showing in your emails
Work through what stops a MailAdx or InboxBanner ad, from a missing tag to no eligible demand.
Start by finding out which of these you're seeing. If the tag is in the email but no ad is visible, the email may be working: when no ad is eligible, MailAdx returns a 1×1 transparent image, and readers see nothing. An empty slot isn't an error, and a filled slot isn't guaranteed on any send.
If the whole email didn't go out, see why a send stopped.
MailAdx checks
| What you see | Likely cause | What to do |
|---|---|---|
| Nothing where the tag was | No default ad unit, so {{MAILADX_AD}} was removed | Set a default under Ad Units → Embed Code |
Literal {{MAILADX_AD}} or a broken block | The tag was mistyped, or pasted into another platform | Place it again. Other platforms need the embed code |
| No ad from another platform | The hash isn't a lower-case SHA-256 | Check the merge tag for your platform. Mailchimp and ConvertKit need a filled custom field |
| Plan message on a tab | Your plan doesn't include ad monetization | See plans and billing |
| No marketplace ads | Your inventory isn't verified, or your grace period ended | Authorize MailAdx with ads.txt |
| No marketplace ads, verified domain | No eligible demand for that open | Nothing is wrong. Lower a high Floor CPM if you set one |
| Direct-sold line item doesn't serve | Its creative isn't approved yet, or the wallet can't cover the fee | See direct-sold orders |
| Ads stopped after working | Demand restricted or serving suspended | See the enforcement section below |
InboxBanner checks
| What you see | Likely cause | What to do |
|---|---|---|
| Link your publisher on the page | No publisher key | Add it in Settings |
| An empty block | The slot is off, or no size is on | Check Admin & inventory → Ad slots |
| A campaign doesn't show | It's paused or stopped, out of its dates, or has reached a cap | Check Campaigns, then View |
| The wrong size or none | The banner has no image for an enabled size | Add a Banner type for that size |
| Few or no fills | Blocking, restriction or a high bid floor | Review the inventory controls |
| Broken images on your domain | Tracking domain DNS or HTTPS isn't working | See the tracking domain guide |
Enforcement
We monitor network health. Under the policies, programmatic demand can be restricted, ad serving suspended, payout balances withheld or accounts terminated. Common triggers are:
- High rates of invalid traffic, even when it isn't deliberate. The Invalid Traffic Policy says we'll work with non-fraudulent accounts on template layouts or list segments.
- High bounce or spam complaint rates. The Monetisation Policy expects complaints typically under 0.1%.
- Purchased, rented or scraped lists, or anything else outside the eligibility rules.
You can appeal within 30 days by emailing policy@influencerskit.com with supporting data.
Still stuck
