Your Postmark sends and bounces, kept long after Postmark drops them

BlinkMetrics reads your Postmark server on a schedule you set and turns it into emails sent, emails bounced and bounce rate, split by message stream. Every row is stored, so your history keeps building after Postmark's 45 day window closes.

Postmark tells you what happened this month. It cannot tell you what changed since March.

Sends drop to zero on one message stream and nobody notices until a customer asks where their receipt went. A bounce rate climbs for six weeks and the first real sign is a mailbox provider throttling the domain. Both are obvious in a dated line. Neither is obvious in a page that starts again every 45 days.

Postmark alone Postmark + BlinkMetrics
How long the detail lasts
  • 45 days by default. Postmark stores email content, events and metadata for 45 days, then deletes them. The Retention Add-on moves that anywhere from 7 to 365 days, but it is an account-wide setting and it applies only to mail sent after you change it.
  • Kept from your first sync. Every row we read is stored and never dropped. Daily sends, bounces and bounce rate load from your stream's first day with mail, and individual bounce records keep accumulating from the day you connect instead of rolling off.
Getting the numbers out
  • 500 rows at a time. Activity exports up to 500 records to CSV. Postmark's own answer for anything longer is to build it yourself: "If you need more than 45 days, you can use our messages API to download and store more history locally."
  • Already pulled. That is the thing we built. Your mail syncs on a schedule, writes to your warehouse and walks the date range in windows, so nothing is truncated at Postmark's 10,000 record ceiling.
Slicing the volume
  • Date, tag and stream. The statistics endpoints accept fromdate, todate, tag and messagestream, and nothing else. If your mail is not tagged, there is no breakdown by what the email actually was, or by which address sent it.
  • Stream and bounce type, out of the box. Filter any metric to specific message streams, and narrow Emails Bounced to hard, soft, transient, blocked, DNS or DMARC, bad address, or several at once. Your subject and sender rows sync into the warehouse too, so your analyst can build the by-email-type view the statistics page cannot.
Knowing something broke
  • A Monday digest and a colour. Postmark emails a digest each week per server and turns the rate orange or red as it nears the limit. We found no way to set your own line on a rate and be told when it crosses.
  • A threshold you set. Put a line on Bounce Rate or Emails Sent, pick the period to measure it over, and BlinkMetrics emails whoever needs to know when the number crosses it, including people who have no Postmark login.
More than one server
  • One at a time. A Server API Token reads one server, and each server reports its own stats. A team running separate servers for production, staging and each client reads them one by one, and gets a separate digest for each.
  • Side by side on one dashboard. Add a connection per server and put their tiles on the same screen, so production, staging and every client site are one view instead of five browser tabs.
Email next to the rest of the business
  • Postmark only. The statistics page reports the mail. It cannot show what the mail did, so send volume never sits beside the signups, orders, revenue or support tickets that explain it.
  • Blended. Sends, bounces and bounce rate sit on one dashboard with Stripe, HubSpot, Shopify, QuickBooks and your support tool.

What BlinkMetrics reads from your Postmark server

You paste one Postmark Server API Token. From then on your mail syncs on its own.

  • Three ready-made metrics. Emails Sent, Emails Bounced and Bounce Rate. A day with no activity reports as 0 rather than a gap, so a stream that stops sending shows up as a flat zero instead of a line that quietly ends.
  • Every message stream, separately. Transactional and broadcast mail are read per stream, so a spike or a drop is traced to the stream that caused it rather than hiding inside a server-wide total.
  • Bounces you can take apart. Narrow the count to hard, soft, transient, blocked, DNS or DMARC failures, or bad addresses. Click the number and you get the individual bounces behind it, with the recipient, the reason and the subject line.
  • A number that matches your dashboard. Emails Bounced counts what Postmark counts as bounced, so unsubscribes, auto-responders and spam complaints stay out of it. Tick one box to fold in send requests Postmark rejected as malformed.
  • Open and click rates, built with you. Daily opens, unique opens, clicks and unique clicks arrive per message stream, with the count of emails sent with tracking on as the denominator a rate needs. Your analyst turns those into your engagement view during onboarding.
  • The rest of it in your warehouse. Spam complaints, the suppression list and one row per outbound email with its tag, subject and sender sync alongside the metrics, ready to build on.
  • Client ready. Send a client a link and they paste their own Postmark token. They never need a login to your workspace, and you never handle their credentials.

Read-only by design. BlinkMetrics sends no mail, edits no streams and changes nothing in Postmark. Recipient addresses, IPs and precise locations are left behind on everything except the bounce records your drilldown needs, and you can revoke the token from Postmark whenever you like.

Complete visibility in 30 days. We will build your Postmark reporting dashboard.

Questions from teams sending through Postmark

These are the questions we get most often, and we would rather answer yours on a quick call.

  • What do you pull from Postmark?

    Your outbound mail. Three metrics are ready to use the day you connect: Emails Sent, Emails Bounced and Bounce Rate, filtered by message stream and by bounce type. Your opens, clicks, spam complaints, suppression list and one row per email sent come across too, which is what open and click rates and your by-email-type views get built from.

  • How far back does the history go?

    Two answers. Daily sends, bounces and bounce rate load from your stream's first day with mail, because Postmark keeps those aggregates forever. The individual bounce records behind the drilldown are different: Postmark only serves those inside your retention window, so that list starts shortly before your first sync and grows from there. Connect sooner and you keep more.

  • Will the numbers match what I see in Postmark?

    Close, and we will tell you where they differ. Emails Bounced uses Postmark's own definition of a bounce, so it lines up. Two honest caveats: a weekly or monthly Bounce Rate is the average of the daily rates, so on a sender whose volume swings it will not exactly equal the volume-weighted rate on Postmark's dashboard, and Postmark buckets its daily counts on its own day boundary rather than your workspace timezone, so a single bounce can show up on the day either side.

  • Can I report on open and click rates?

    Yes, your analyst builds them with you. Daily opens, unique opens, clicks and unique clicks sync per message stream, alongside the count of emails sent with tracking on, which is the denominator a rate needs. They are built during onboarding rather than picked off a list, and Postmark keeps these daily totals permanently, so your open and click rates go back as far as your mail does. Only the per-email detail of which individual message was opened is bounded by Postmark's retention window. The rates are not.

  • I send from more than one Postmark server. Does that work?

    Yes, one connection per server. A Postmark Server API Token reads exactly one server, so a separate token means a separate connection. Their tiles then sit on the same dashboard, which is the part Postmark's own stats page will not do for you.

  • Who needs to connect it, and what if that is not me?

    Whoever holds the Server API Token. If that is a client or a colleague, we send them a single-use link where they paste their own token. They never get a login to your workspace, and the token is not the account-level one, so it cannot create or delete servers.

  • How often do the numbers update?

    You choose. Syncs run as often as every 8 hours, a tighter floor than we set for most sources because this is one you would want to catch a problem on, and your dashboard shows when it last refreshed.

What customers say

I was worried I was going to have to do it myself. So, having you build us a custom reporting dashboard is perfect, and it'll auto-update!
