A Free Brevo Dashboard: Which Domains Actually Open Your Emails

Someone on the Brevo community forum asked a question that sounded simple:

"We want to know which domains are opening our emails. The only way I can see to do this is to download the CSV of «Opens breakdown by domains» for each campaign, one at a time, aggregate and then query that table. Does anyone know of a more efficient way to do this? I am not a developer, but all ideas welcome."

It's a good question — and the manual answer (export one CSV per campaign, then stitch them together by hand) is exactly the kind of busywork software should remove. So I built a small, free tool that does it for you: a Brevo dashboard that aggregates opens-by-domain across every sent campaign in your account.

What it shows

You paste a Brevo API key, and the dashboard pulls the per-domain stats Brevo already tracks — then sums them across all your campaigns and ranks the result:

• Every recipient domain, ranked by unique opens — Gmail, GMX, web.de, T-Online, Outlook, iCloud, your own domain, and the long tail rolled into an "other" bucket.
• The numbers that matter per domain — delivered, unique opens, open rate, clicks, bounces, unsubscribes.
• Share of audience — what fraction of your delivered mail and your total opens each domain represents.
• Filters — by date range, campaign name, or minimum recipient count, so you can compare a newsletter against a launch sequence, or this quarter against last.
• CSV export — the full aggregated table in one click, for your own analysis.

For a German-audience account, the picture is often striking: a handful of consumer mailbox providers (Gmail, GMX, web.de) account for the overwhelming majority of opens, while open rates can differ sharply by provider. That's the kind of pattern you simply can't see one campaign at a time.

Your key stays private

The Brevo API key you enter is held only in your encrypted browser session — never written to a database, never logged. For peace of mind, create a disposable, read-only Brevo API key for the tool and delete it afterwards. There's a "Forget my key" button that clears it instantly.

The Brevo + Zoom background

Why is a webinar company building Brevo analytics? Because ManyMeet lives right at the seam between Brevo and Zoom.

ManyMeet turns ordinary Zoom Meetings into personal sales webinars and keeps all the email logic — confirmations, reminders, and behavior-based follow-ups — inside Brevo, where your marketing already lives. No second webinar platform, no scattering your contacts across five tools. (That origin story is its own long tale of frustration.)

Because we sit on top of Brevo email marketing data every day, advanced Brevo stats are important to us — and to the hosts who run webinars through ManyMeet. Opens-by-domain was simply the first one worth packaging up and sharing.

Tell me what else you'd like to see

This is meant to grow. If there's a view of your Brevo data you wish existed — engagement trends over time, list health, per-domain deliverability, re-engagement candidates — I'd genuinely like to hear it. The opens-by-domain dashboard exists because someone asked; the next one can too.

Reach me through the contact page or just reply to any ManyMeet email.
