What is the best time to send email?

There is no universally verified best time — commonly-cited general guidance points to weekday mornings and midday in the audience’s local timezone, but these are not measured open-rate facts. This free planner converts those guidance bands into your timezone; your own list’s past open data is always a better guide than any general band.

Yes — this best time to send email planner is completely free with no signup. Enter the sender and audience timezones plus your cadence to get converted send slots, each labeled honestly as general guidance rather than verified fact.

What is Best time to send email?

Email Send-Time Planner — Find the best time to send email with this email send time planner — send slots in sender-local and audience-local times for every band. Try it now!

The planner converts four commonly-cited audience-local time bands (morning 8–10 AM, midday 11 AM–1 PM, afternoon 2–4 PM, early evening 5–7 PM) into your timezone using pure Intl date math — no AI, no network. These bands are general guidance from common industry discussion, NOT verified open-rate facts: the tool never presents open-rate percentages and never claims research-backed optimal times. Offsets are computed for one fixed reference date (2026-10-01) so results are deterministic; the outputs warn that daylight-saving changes can shift real send times by an hour.

Good to know

All "best time" bands are commonly-cited general guidance, NOT verified open-rate facts — no open-rate percentages are presented or implied.
Timezone offsets use a fixed reference date (2026-10-01) for deterministic results; daylight-saving shifts can move real conversions by an hour.
Send days (Tue/Wed/Thu rotation) are commonly-cited guidance, not a researched optimum for your audience.
