The best time to send email
The best time to send email is usually mid-morning on a weekday, around 9–11 a.m. in the recipient’s local time zone. Tuesday and Thursday are the most consistently cited days. Use that as a test plan, not a rule: the best time for your list depends on who your subscribers are and where they live.
Best time by day of week
These are general industry reads, not guarantees. Treat every figure as a hypothesis to test against your own list, and keep any third-party number labeled until you can verify the original source.
What the studies say. Recent 2025–2026 analyses converge on a weekday, daytime window of roughly 9 a.m. to 3 p.m. local time, with mid-morning (~10 a.m.) and mid-afternoon (~3:30 p.m.) the most-cited peaks; Omnisend finds Tuesday–Thursday lead on opens. They disagree at the edges, which is the point: MailerLite’s analysis of 2M+ campaigns (Dec 2024–Nov 2025) put the single highest click rate at Friday 8 a.m. (~12%). Treat the window as a hypothesis and test your own list.

Best time by audience type
B2B
Weekday business hours win. Tuesday through Thursday, mid-morning, lines up with when people are at their desks and triaging work.
B2C
Evenings and weekends often outperform. People check personal inboxes outside of work, so 6–9 p.m. and weekend mornings are worth testing.
Newsletters
Consistency beats optimization. Pick a regular slot your readers can anticipate and protect it; a dependable rhythm builds the habit that drives opens.
Product, lifecycle & transactional
Time by behavior, not the calendar. These messages should fire from the user’s action: a signup, a milestone, or an abandoned step. The trigger is the timing.
Why best time is really about your audience
A single global send time is the wrong goal. The method that actually works is repeatable:
Segment your list by behavior, region, and engagement so timing reflects real groups, not an average.
Use time-zone-aware sending so 9 a.m. means 9 a.m. for each recipient, not for your office.
A/B test send time on a meaningful sample, then roll the winner out to the rest.
Operationalize behavior-based timing with Loops workflows so lifecycle messages send on each user’s action.
The honest take: timing matters less than it used to
Replace the placeholders below with real figures from your own Loops account before publishing.
An email sent at 4 a.m. Monday usually just waits at the top of the inbox until someone looks around 8 a.m. The hour you send rarely decides whether it gets read.
Relevance beats the clock. The right message to the right person is what gets opened, so fix segmentation and content first.
Local-time delivery matters more than the exact hour. Time-zone-aware sending keeps you out of the 3 a.m. slot where you’d be buried by morning.
Behavior-triggered emails arrive when someone is already engaged, no calendar guess required.
Common myths
There is one universal best time. Timing is audience-specific; an average hides the groups that matter.
Never email on weekends. For many B2C lists weekends perform well, so test before you assume.
Optimization beats relevance. A perfectly timed but irrelevant email still loses to a relevant one.
Set it and forget it. Audiences and behavior shift, so revisit your timing periodically.
Opens tell the whole story. Apple Mail Privacy Protection inflates open rates, so lean on clicks and conversions too.
