What is Answer rate?

  • Also called: pickup rate, call answer rate

Reviewed by Sujan ThapaliyaLast updated

Definition

Answer rate is the share of calls that are picked up at all, by a person or a machine. It is a deliverability measure rather than a sales one: it tells you whether calls are reaching handsets and being treated as worth answering.
The three STIR/SHAKEN attestation levels, which underpin how answer rate behaves in practice: A asserts both that the carrier knows the customer and that the customer may use the calling number, B asserts the customer only, and C asserts neither. A shared number pool can reach B at best, which is why number ownership keeps recurring in these definitions.
Attestation is the backdrop to most caller-ID and deliverability terms, answer rate included.

In practice

How answer rate actually works

Because it includes voicemail, answer rate moves for different reasons than connect rate. A number that has started being labelled will show a falling answer rate before anyone notices the drop in conversations.

Watched per number and per day, it is the earliest available warning of a reputation problem — usually a week or more before the effect is visible in pipeline.

Answer rate also varies by time of day and by region far more than most teams assume, which is why campaign-level averages hide the pattern that would let you fix it.

Answer rate also moves with time of day far more than most teams measure. The same list called at 8am and 4pm in the recipient's own zone can differ by several points, which is a scheduling decision rather than a deliverability one and costs nothing to test.

Worked example

Answer rate on one number falling from 22% to 9% over four days, while other numbers hold, is a labelling problem. The same fall across every number is a list problem.

Answer rate: common questions

What causes answer rate to drop suddenly?
Almost always number reputation: a label applied by carrier analytics, or a block. A gradual drift is usually list decay; a cliff is nearly always the number.
Is answer rate the same as connect rate?
No. Answer rate includes voicemail and anyone picking up; connect rate counts live humans only. Both matter, and they fail for different reasons.
How often should answer rate be reviewed?
Daily, per number. It is the cheapest early warning available for deliverability, and it stops being useful the moment it is averaged across a campaign.

Branded caller ID puts your business name on the recipient's screen instead of a bare number. In North America it works through CNAM, the caller-name record attached to a number, combined with STIR/SHAKEN signing that lets the terminating carrier trust the call is really from you.
