How to Analyze a Campaign After Sending

May 9, 2026 4 min read 81

Launching a campaign is only half the battle. Next comes analysis. Without regularly analyzing metrics, you can't understand which topics work, which day of the week gives the best open rate, and where your SMTP reputation is drifting.

1 Hour After Launch

Open the campaign dashboard. What should be normal:

  • Sent > 0 — sending is in progress. If 0 — check the campaign status and SMTP in the dashboard
  • Bounce rate < 5% on the first hundred emails. If higher — pause, check the database
  • Open rate > 15% on the first hundred delivered. Less — most likely the subject line or ending up in spam

If something critical happens, the campaign can be paused via the button in the campaign list, investigated, and continued.

24 Hours Later

Most emails have been delivered and opened. Look at the final numbers:

  1. Open rate, click rate, reply rate — record in a table for comparison with other campaigns
  2. "Replies" section — go through the positive responses, respond to the hottest ones. AI-classification shows confidence — for responses with confidence > 0.85, you can set up automatic follow-up without confirmation
  3. Bounce list — export via API or manually, exclude these addresses from future campaigns

1 Week Later

Long openings and late replies. Some people open on weekends, some after returning from vacation. The final picture usually stabilizes after 5-7 days.

At this stage:

  • Compare with previous campaigns — which topics give the best open rate
  • Check the reply rate by segments — maybe some database segments respond better than others
  • Launch a follow-up for those who opened but did not reply (if you use this tactic)

Graphs on the Main Dashboard

On the main dashboard page, there is a "14-Day Dynamics" graph — showing sent/opens/clicks by day. Helps to notice trends: if the open rate is slowly falling — the SMTP reputation is most likely degrading, a warmup break or switching to other accounts is needed.

SMTP Capacity and Distribution

The SMTP capacity widget shows how much of the limit has been used today. If you are hitting 100% of the daily limit — it's time to connect more SMTP accounts. For large volumes, it is reasonable to keep a reserve of 30-40% of the limit so as not to peak.
