Measure your sends and keep your list healthy (Reports and Suppressions)

Updated 2026-07-13

In two lines: in Reports you see how each send performed; in Suppressions are the contacts who no longer receive emails. The two views together tell you whether your email works and protect your sending reputation.

Where do I see how my sends performed?

In Email Marketing > Reports. It's organized into tabs:

  • Summary — the general snapshot of the latest sends.
  • Campaigns — the performance of each campaign.
  • Flows — how your automated flows are doing.

Use it to compare subjects, audiences, and content, and keep what works best.

The two key metrics: opens (how many opened the email) and clicks (how many clicked a link). They go up when the subject and content are relevant for that audience.

What are Suppressions?

In Email Marketing > Suppressions are the contacts you do not send to: they're added on their own when someone unsubscribes or when an email bounces permanently. You can also add an email by hand.

Keeping this list isn't a problem, it's hygiene: continuing to send to addresses that bounce or to someone who unsubscribed damages your reputation and makes your emails land in spam for everyone else.

Don't forcibly resend to a contact suppressed by bounce: if their address doesn't exist, insisting only worsens your deliverability.

Why didn't a contact receive my campaign?

Almost always because they're in Suppressions. Look for them there: if they unsubscribed, respect the decision; if it was a one-off bounce and you know the address is valid, you can remove the suppression. If the problem is that no email arrives, check My emails land in spam or don't arrive.
