You can write a flawless questionnaire and still watch it sink under a pile of unread email. The best time to send a survey often decides whether people answer at all. Most invitations win or lose attention within a few hours of arriving.
In this blog, we break down the best days and hours to send a survey. We also cover what our platform data shows, timing by survey type, and the mistakes that quietly drain responses.
What is the best time to send a survey?
The best time to send a survey is midweek, Tuesday through Thursday, between 9 am and 11 am in the recipient’s local time zone. This window catches people after they have cleared their morning inbox but before meetings take over the day.
QuestionPro platform data points the same way:
- Tuesday is the most common send day across millions of invitations, closely followed by Monday.
- Mid-morning, between 10 am and 11 am, is the most common send hour.
- Tuesday sends also come back the fastest, with the shortest average completion times of any day.
Treat this window as your starting benchmark, then test it against your own audience.
Why does survey timing matter for response rates?
Survey timing matters because response rates are already thin, and a poorly timed invitation makes them thinner. Survicate’s 2025 benchmark analysis of more than 4,300 surveys found a median response rate of just under 10%. Every avoidable loss hurts.
A well-timed send protects three things at once:
- Visibility: An invitation that arrives when inboxes are quiet stays near the top instead of getting buried by lunchtime.
- Completion speed: People who open a survey during a natural break tend to finish it in one sitting rather than abandoning it halfway.
- Data quality: Reaching your full audience, not just the always-online segment, keeps your sample balanced and your results closer to a good survey response rate.
Timing will not rescue a bloated 40-question survey. It simply removes one of the cheapest, most fixable barriers between your invitation and a completed response.
What is the best day of the week to send a survey?
Tuesday is the most reliable day to send a survey for US audiences, with Monday a close second. The research is not unanimous, though. Weekdays beat weekends by a wide margin, while the gaps between individual weekdays are smaller than most people expect.
| Day | What the data shows |
|---|---|
| Monday | SurveyMonkey’s analysis of 100,000 surveys found Monday sends collected about 10% more responses than average. |
| Tuesday | Most popular send day in our platform data, and the day with the fastest completions. |
| Wednesday and Thursday | SurveyMonkey’s State of Surveys report shows they receive the highest share of submissions, at 17.7% and 17.9%. |
| Friday | The weakest weekday. Friday sends earned roughly 13% fewer responses than average in the same SurveyMonkey study. |
| Saturday and Sunday | Lowest send volume and slowest completions overall, with exceptions for consumer and mobile audiences. |
Survey administrators also shape this pattern. Many teams build and test on Monday, then launch on Tuesday, which is part of why Tuesday dominates send volume.
What time of day should you send survey emails?
Send survey emails between 9 am and 11 am local time for the most dependable results. That mid-morning band shows up consistently across our platform data and independent studies of email surveys.
A few send windows are worth knowing:
- 9 am to 11 am: The safest default. Recipients have triaged urgent email and can spare five minutes.
- 6 am to 9 am: The runner-up in our platform data. Your invitation waits at the top of the inbox when the workday starts.
- 3 pm to 6 pm: A useful secondary window for consumer audiences, who often clear personal email on their phones late in the day.
- Overnight sends: Zendesk data summarized by HubSpot found response rates peaked around 4 am, when inbox competition disappears, even though the largest absolute number of responses still arrives midday.
Whichever window you pick, schedule by the recipient’s local time. A 10 am send from New York lands at 7 am in California, which changes the result.
Does the week of the month matter for survey timing?
The week of the month matters less than the day and hour, but activity still clusters in a clear pattern. In our platform data, survey distribution and completions run highest in the last week of the month. Week two is the quiet point.
The rhythm follows how research teams actually work. Early in the month, teams launch projects finalized the month before. Mid-month shifts toward building questionnaires and analyzing incoming results. By week four, finished surveys go out the door before monthly reporting begins.
The practical takeaway: there is no penalty for sending mid-month. If anything, your invitation faces less competition from other surveys landing in the same inboxes.
What’s the difference between open rate, response rate, and completion rate?
These three metrics get confused constantly, and each one tells you something different about timing. Open rate is an email metric, while response and completion rates measure actual survey behavior. Judging a send time by opens alone can mislead you.
| Metric | What it measures | Why it matters for timing |
|---|---|---|
| Open rate | Percentage of delivered invitations that get opened | Shows whether your send time and subject line won attention. |
| Response rate | Completed surveys divided by total invitations sent | The truest test of a send window’s overall performance. |
| Completion rate | Percentage of people who start the survey and finish it | Reveals whether respondents had enough time when they clicked. |
A send time can produce strong opens and weak completions. That gap usually means people saw the invitation at a busy moment. Comparing completion rate against response rate tells you whether to fix your timing or your questionnaire.
What is the best time to send a survey by survey type?
Each survey type reaches an audience with a different daily rhythm, so the ideal send time shifts too. The midweek morning benchmark still applies, but three categories deserve their own rules.
Customer experience surveys
Customer surveys perform best when triggered by the customer journey rather than the calendar. The event itself, not the day of the week, sets the clock.
- Send transactional feedback requests, such as a post-purchase or post-support survey, within 24 hours of the interaction while it is still fresh.
- Schedule relationship studies, such as quarterly NPS (Net Promoter Score, a loyalty metric based on how likely customers are to recommend you), for midweek mornings.
- Keep automated triggers consistent so every customer is measured at the same point in their journey.
Employee surveys
Employee surveys do best on Monday or Tuesday, sent early morning or mid-afternoon during working hours. Those days align with when work email engagement peaks. They also give staff the full week to respond before weekend drop-off. The same weekday logic applies to a full engagement study or a short eNPS pulse, the employee version of Net Promoter Score.
Market research and community surveys
Highly engaged research communities are the exception to nearly every timing rule. In our platform data, community members respond steadily across weekdays and even weekends. They have opted in, so they expect invitations.
- B2B (business-to-business) panels still favor the workweek, since members respond from their desks.
- B2C (business-to-consumer) communities answer at almost any hour, including evenings and weekends.
- The more engaged your audience, the less send timing matters, which makes long-term panel relationships a timing strategy in themselves.
How do you find the best time to send your survey?
The fastest way to find your own best send time is a split test against the benchmark window. One afternoon of setup gives you evidence instead of guesswork.
- Set the control.
Use Tuesday through Thursday, 9 am to 11 am local time, as your baseline send window.
- Split your list.
Divide your audience randomly into two or three groups and send the identical invitation at different times, changing nothing else.
- Size each group properly.
For large populations, roughly 385 completed responses per group gives a 5% margin of error (the accuracy range around your result) at 95% confidence. A sample size calculator does the math, and it helps to know how many survey responses you need overall.
- Measure the right numbers.
Compare response rate, completion rate, and the share of responses arriving within 48 hours for each send window.
- Lock in the winner and retest.
Adopt the strongest window, then rerun the test twice a year, since audience habits drift.
What survey timing mistakes lower response rates?
The most common timing mistake is sending on Friday afternoon or over the weekend to a professional audience. Those invitations go stale before Monday. Several other errors are just as costly and just as avoidable:
- Ignoring time zones.
The US alone spans four continental time zones, so one batch send at “10 am” reaches a quarter of your list before 8 am.
- Launching during holidays.
US response rates sag around Thanksgiving week, late December, and the July 4th stretch, when inboxes go unattended.
- Rushing the reminders.
A follow-up the very next day reads as nagging. Space reminders a few days apart and cap them at two.
- Competing with yourself.
A survey that lands the same morning as your marketing newsletter fights your own brand for attention.
- Testing once and never again.
A winning window from 2023 may quietly stop working as your audience or their work habits change.
Fixing these costs nothing. That makes timing one of the easiest ways to boost response rates for online surveys.
Making survey timing work for your next project
There is a real best time to send a survey: midweek, mid-morning, in the recipient’s local time zone. What the data adds is nuance. The right window bends with your audience, your survey type, and how engaged your respondents already are.
Keep three principles in front of you:
- Start from the Tuesday-to-Thursday, 9 am to 11 am benchmark rather than a guess.
- Let the survey type override the calendar, especially for event-triggered customer feedback.
- Treat every send as a data point, and let split tests refine your window over time.
Timing will never substitute for a relevant topic and a respectful survey length. Get all three right, and even a questionnaire that once limped along can become the one your audience actually answers.
Frequently Asked Questions (FAQs)
Avoid weekends for professional audiences, since unread invitations go stale by Monday. Consumer surveys can work, though: SurveyMonkey found 24% of mobile survey takers respond on weekends, versus 20% on desktop.
Wait two to three days after the original invitation. Send the reminder at a different time of day to catch people your first send missed. Limit yourself to one or two reminders total, since extra nudges annoy more than they convert.
Yes, always schedule by the recipient’s local time, not your own. Most survey platforms can stagger delivery automatically. Each segment of a national list then receives the invitation inside the same optimal mid-morning window.
Keep most email surveys open for one to two weeks, which leaves room for a reminder and late responders. Transactional feedback surveys can close within a few days, because responses collected long after the interaction lose accuracy.
No single month wins, but timing around US holidays matters. Response rates dip during Thanksgiving week, late December, and early January. Schedule major studies for stretches when your audience follows a normal working routine.
