Reading a campaign report like a pro

Opens, clicks, devices, mail apps and timing — what each number means, and which ones deserve your attention.

Every campaign gets a report that fills in as people read. Open it from Analytics›Campaign History.

Opens: a signal, not a count

Opens are counted from a tiny image in the email. Some mail apps load images automatically, and some block them, so treat opens as a direction — up or down compared with your usual — rather than an exact number. Devlo filters known bots and early scanner opens to keep it as honest as possible.

Clicks: the number that matters

A click is a person choosing to act. Security scanners in company mail systems often “click” every link before a human sees it; Devlo leaves those out, so the clicks you see are people.

Devices and mail apps

The report shows mobile versus desktop and which mail apps were used — Gmail, Outlook, Apple Mail, Yahoo. If most readers are on phones, keep your emails short and your buttons big.

Timing

Analytics›Send Times turns your opens into a heatmap of hours and days. Send the next campaign when your audience actually reads.

What to do next

  • Compare with your last five campaigns, not with industry averages.
  • Follow up with the people who clicked — they raised their hand.
  • Move the quiet ones toward Re-engagement.
  • Export the report to CSV when you need it elsewhere.
