Email Analytics and Sender Reputation
Deliverability, engagement and sender health for one brand.
What It Is
Communication > Email > Analytics & Reputation is the health report for one brand's email sending. It answers two different questions on one page.
How is my email performing? How much went out, how much bounced, how many people opened and clicked, on what kind of device.
Am I a sender inbox providers will keep accepting? That is the reputation half, and it is judged on just two numbers: your bounce rate and your spam complaint rate.
The screen needs a verified sending domain. Without one it shows a short card offering to take you to Senders instead, because there is no sending history to report on yet.
Why It Matters
Inbox providers decide whether to accept your mail based on how you have behaved in the past. Two signals carry most of that weight, and both are on this page.
Bounces say you are mailing addresses that do not exist, which suggests a list you have not maintained. Spam complaints say recipients did not want what you sent. Enough of either and your mail stops reaching inboxes — not only the campaign that caused it, but everything you send afterwards.
This matters more in Zyntro than in a tool you use occasionally, because Segmentation Intelligence keeps engaging contacts over months. A reputation problem compounds quietly. Opens and clicks tell you whether your message landed well; bounce and complaint rates tell you whether you will be able to send at all next month.
How It Works
Metrics are read live from your brand's own sending infrastructure each time the page loads. Nothing is cached, so what you see is current.
Two filters control most of the page. Period covers the last 7, 30 or 90 days, the last 12 months, all time, or a custom range. Stream narrows to one message stream — typically your transactional stream or your broadcast stream — or shows them together.
Reputation is derived, not reported. Zyntro compares your bounce rate and spam rate against deliverability thresholds and shows a banner: healthy, needs attention, or at risk. The overall verdict always follows the worse of the two. With nothing sent in the period, there is no verdict to give and the banner says so.
The opt-out list is current state, not history. Everything above it describes a date range; the suppression list describes who cannot be emailed right now. A suppression stays until something removes it, so that section does not change when you change the period.
Examples
A healthy sender after a month of nurture email
Bounce rate 0.4%, spam rate 0.02%. The banner is green, and both the bounce and spam figures are shown in their healthy colour. Open rate is worth reading for message quality, but nothing here needs action.
A freshly imported list pushes bounces up
A few hundred imported contacts are mailed and bounce rate jumps to 6%. The banner turns red and says to clean the list and pause risky sends. The bounce breakdown chart separates hard bounces — addresses that do not exist — from soft ones, which is how you tell a bad list from a temporary problem.
Opens look low and nothing is wrong
Open rate is measured against everything sent, and an open is only recorded when the recipient's email client loads the tracking pixel. Many clients block that by default, so a low open rate can reflect privacy settings rather than a bad subject line. Clicks are the firmer signal.
A period with no sends
The charts and performance figures empty out and the banner reports that there is not enough data. The opt-out list stays visible, because who is suppressed has nothing to do with the date range you picked.
Important: Opening this page keeps your CRM in step with your suppression list: any contact whose address has been suppressed is marked as opted out of email, so future sends skip them. The page tells you when it has changed anything. Nothing is ever opted back in automatically.
