What to watch in the report: replies or opens
Published 2026-08-08
Short answer
The main signal is a substantive reply or call—not open rate. An open on a general inbox may only mean the mailroom saw the message. Sales cares about dialogue: a question, a reasoned no, a request for materials.
Why is open rate misleading here?
Mail can be opened while sorting inbound and never forwarded. Open tracking is noisy: some clients block images, some skim in preview. High opens with zero replies are not a win.
The reverse also happens: a real reply with a quiet open—someone answered from a phone or forwarded a colleague. Steer by inbound touches.
What counts as success for sales?
A product question, a proposal request, a handoff to procurement, a meeting, a clear no (“we already have a vendor”). That feeds the next step or a sharper segment.
Product estimate: on a relevant segment about 3–5% real leads of send volume (internal observations as of August 2026, not an independent benchmark). Reply quality beats chasing the average.
How do you read silence after a wave?
Silence on a wide segment usually means “no pain match,” not “channel dead.” Tighten industry or region, rewrite the opening, check exclusions.
A simple weekly set: sent, replies and calls, tags interest / no / wrong person, one-line takeaway—what changes in segment or copy. Enough to run outreach as a sales experiment.
FAQ
- Should you chase above-market open rate?
- No. For this channel opens are secondary. Watch replies and next steps in the deal.
- What about auto-replies and out-of-office?
- Count them apart from real leads. The address is live—but there is no dialogue about the offer yet.
- How do you compare two letter wordings?
- Same segment, similar volume, different copy. The winner has more substantive replies—not a higher open rate.
