What do the numbers in Newsletter Analytics mean?

Newsletter Analytics shows what each platform reports at the moment you sync. Each sync is saved, which is what builds your growth chart.

Summary cards

  • Total Subscribers: the latest subscriber count of every connected list, added together.
  • Avg Open Rate and Avg Click Rate: the average of the rates for the lists that report them. Lists that don't report rates are left out. The open rate turns green at 20% or more and the click rate at 3% or more.
  • Lists Connected: how many lists you've connected.

Growth chart

Subscriber Growth has one line per list, with a dot for every sync. When you have two or more lists, a dashed Total line shows the combined count. A newly connected list adds to the total from its first sync, so it shows as a step up rather than a dip.

What each platform reports

  • Mailchimp: subscribers in the chosen audience (only people with a subscribed status), plus Mailchimp's open, click and unsubscribe rates for that audience and its campaign count.
  • Kit: all active subscribers in your account. Open and click rates are averaged over your most recent broadcasts (up to 10).
  • MailerLite: all active subscribers in your account. Open and click rates are averaged over your 10 most recently sent campaigns.
  • Beehiiv: active subscribers to the publication, plus Beehiiv's average open and click rates.
  • EmailOctopus: subscribed contacts on the chosen list. Open and click rates are averaged over your most recent campaigns (up to 10).
  • Sendfox: contacts on the chosen list, plus the list's average open and click rates.
  • Flodesk: active subscribers in the chosen segment. Flodesk doesn't report open or click rates.
  • Brevo: subscribers on the chosen list. Open, click and unsubscribe rates come from your 20 most recent sent campaigns. Brevo only keeps statistics for the last six months.
  • Sendy: active subscribers on the list only. Sendy's API doesn't report open or click rates, so its card says "Subscriber count is the only metric Sendy's API reports."

A dash means the platform didn't report that number.

When the numbers update

The numbers change only when a sync runs: when you click Sync Now or Sync All, or automatically when the account owner opens the page and a list hasn't been synced for more than six hours. A card that has never synced says "No data yet — sync to fetch stats."
