The Speed Chart in the Campaign Report and What to Do

Estismail does not send separate emails about pauses and stops: the whole sending history is recorded in the campaign report, on the "Sending speed" chart at the bottom of the page. Once you learn to read it, you can see in half a minute how the campaign went at each provider and whether anything was wrong.

How to read the chart

Each line on the chart is one provider, with its name at the end of the line. The height of the line shows how many emails per minute went to it. The color tells you your domain rating at that provider: the darker the line, the higher the rating and the faster the ramp-up. A light gray line labeled "no ramp-up" is a lane whose speed did not depend on the rating, usually the German and other providers.

A calm campaign looks simple: a white circle labeled "test batch" at the start, then the line climbs steadily. Other marks appear only when the provider has said something:

• a yellow triangle, "step back": the provider deferred some emails or asked for a slower pace, the speed was lowered, but sending did not stop;
• a yellow diamond, "pause": the provider started rejecting emails, sending to it was halted, the line drops to zero, and after the pause a "test batch" is visible again;
• a red square, "stop": the provider kept rejecting emails even after several pauses, and sending to it was stopped completely.

If you hover over a point, you see the time, the provider, the number of emails per minute and what happened in that minute. And under the chart, one sentence per provider gives the main point: which test batch it started with, what speed it reached, and whether there were pauses and a stop. Why it all works this way is explained in the articles on test batch and ramp-up and on pauses, retries and stopping.

If sending to a provider stopped

Most often a red square means the provider did not like the campaign itself: the email or the address list. The easiest way to sort it out is this:

1. Look in the campaign report at the mail server answers from this provider. What each answer means is written in the articles on mailbox providers.
2. Check your list. Subscribers must have agreed to receive your emails themselves. If you have not written to them for more than six months, send first to those who opened emails recently. Remove addresses that do not exist or have never opened an email. Many "address does not exist" rejections in the report mean the list is outdated or was not collected from subscribers.
3. Check your email. A subject without shouting, all caps and promises like "free" and "urgent". The email has text, not just one image. Links lead to your site, with no link shorteners. The "unsubscribe" link is easy to see.
4. Check your domain: SPF, DKIM and DMARC signatures must be connected in the sender settings. How to do it is explained in domains and setup. If the domain is new, start with small campaigns to your most active subscribers.
5. Only after that, send again. The same campaign sent right after a stop will meet the same thing at the provider.
