Webinar Reminder Emails
When should you send webinar reminders, and what should they say?
Some people who register for a webinar do not attend it. Life gets in the way, the registration was weeks ago, or the email with the link is buried. Reminder emails are a simple, direct way to bring registrants back on the day. They take little effort to send, and they do not require anyone to be persuaded of anything: the person already said yes, and the reminder just makes it easy to follow through.
This guide gives a reminder schedule, with timing options labeled as common practice rather than a rule, what each reminder should contain, subject line ideas, copy-ready templates for five emails (confirmation, day before, hour before, starting now and missed it) and how to measure whether it worked. If you are new to the format, start with what a webinar is, and for the running order of the session itself see the webinar run of show template.

Why reminders matter for attendance
Registration and attendance are two separate decisions. A person registers when the topic catches their eye, often days or weeks ahead. Whether they attend depends on what else is on their calendar when the time comes, and whether they remember. A reminder closes that gap.
Reminders also give you a chance to restate the value of the session, repeat the practical details and make joining easy. They help people who want to come, which is why they feel helpful rather than pushy.
The reminder is not a sales email. It is a service message to someone who asked to be there, so keep the tone plain and useful: what, when, how to join. Anything that reads like an advertisement belongs somewhere else.
People forget
A registration made well ahead is easy to lose. A reminder puts the session back in front of the person on the day.
Joining must be easy
The most useful content of a reminder is the link, the time in the person's time zone and how to join.
Reminders suit event emails
Reminders to people who registered are part of running the event: confirmations, reminders and updates. Eventdex's email tools are for those event transactions, and reminders to registrants fit that use.
Event registration softwareNo figure to promise
How much reminders help depends on your audience, your topic and your timing. Measure your own attendance rather than expecting a set result.
A reminder schedule
There is no single correct timing, and the right pattern depends on how far ahead people register. A webinar booked a week ahead needs fewer emails than one booked two months ahead. These are common patterns, so treat them as starting points and adjust to your audience and time zones. Fewer, well-timed emails beat many repetitive ones.
| When | Purpose | Notes | |
|---|---|---|---|
| Right after registering | Confirmation | Confirm the booking and give the details | Include an add-to-calendar link |
| A week before (optional) | Early reminder | Remind people who registered long ago | Skip for webinars booked within a few days |
| The day before | Day-before reminder | Prepare people and repeat how to join | A common timing; includes agenda or what to prepare |
| The morning of | Same-day reminder | Catch people at the start of their day | Useful for early registrants and evening sessions |
| About an hour before | Hour-before reminder | A last nudge with the join link | Keep it very short |
| At start time | Starting now | Bring in latecomers | One line and the link |
| After the session | Replay or missed-it | Offer the recording to non-attenders | Send to registrants who did not attend |
What each reminder should contain
Every reminder has the same job: make it easy to show up. The details change slightly as the time gets closer.
Early reminders can carry more: the agenda, the speaker and what to prepare. Late reminders should carry less. An hour before, a person needs the time and the link, and nothing else.
Name, date and time
State the webinar title and the start time, with the time zone named. For international audiences, link to a time converter or show the local time.
A join link, near the top
Put the link or button where it can be found without scrolling. This is the most important line in the email.
Calendar link
In the confirmation and early reminders, include an add-to-calendar link so the session is in the person's schedule.
What to expect
Two or three lines on what they will learn and who is speaking. Reminders can restate value, not just logistics.
How to prepare
Anything they should do first, such as testing audio, downloading software or preparing a question.
A way out
If they cannot attend, tell them whether a recording will be sent. That reassures them and avoids no-shows who feel guilty.
Subject line ideas
A reminder subject line should be plain and specific. Put the thing and the time first. Avoid anything that looks like a promotion, and avoid pressure tactics.
Confirmation
"You are registered: [webinar title] on [date]"
Day before
"Tomorrow at [time]: [webinar title]"
Hour before
"Starting in one hour: your link for [webinar title]"
Starting now
"We are live: join [webinar title] now"
Missed it
"Sorry we missed you: the recording of [webinar title]"
Keep it honest
Avoid false urgency such as 'last chance' for a webinar with no limit. People notice, and trust matters more than one session.
Copy-ready templates: five emails
These five emails cover the whole sequence. Replace the bracketed text, keep each one short and test the join link before you send.

Sending the emails well
The best-written reminder fails if it is not sent properly. A short checklist avoids most problems.
Send to registrants only
Reminders go to people who registered. Do not add other people to the list, and honor anyone who unsubscribed or asked not to be emailed.
Use the registrant's time zone
A reminder 'at 9 AM' sent in the wrong time zone arrives after the session. Show the time clearly, and think about when you send.
Schedule, do not send by hand
Set up the sequence ahead, so a busy day does not skip the hour-before email.
Test the link
Click the join link from the email, on a phone and a computer, before it goes out.
Check the rules
Email rules differ by country and region, including how to handle consent and unsubscribes. Check with the person responsible for compliance in your organization.
How to measure attendance
Compare your own webinars with each other. Keep the measure the same each time, so changes in the schedule are the only thing that changes.
Attendance rates vary a great deal with the topic, the audience and whether the session is free, so a rate from someone else's webinar tells you little about yours. Build your own baseline over a handful of sessions, then test one change at a time.
Change one thing at a time
If you add the hour-before email, leave the rest alone for that webinar so you can see the effect.
Log it
Record the timing, the audience and the attendance for each webinar, and compare across a few before you decide.

FAQ
Webinar Reminder Emails: common questions
How many reminder emails should I send for a webinar?
A common starting point is a confirmation, a day-before reminder and an hour-before reminder, with a replay email afterward. Adjust to how far ahead people register. Too many can annoy people, and too few leaves the gap that causes no-shows.
Should I send a reminder on the same day?
A same-day reminder, either in the morning or about an hour before, is a sensible starting point because it reaches people when the session is close. Keep it short and put the join link at the top.
Should I email people who did not attend?
Yes, a short replay email to registrants who did not attend is helpful. They asked for the session, and the recording gives them a second chance.
How do I handle different time zones?
Always name the time zone and, if you can, show the time in the recipient's own. Add a calendar link, which converts the time automatically.
Can Eventdex send webinar reminders?
Eventdex's registration software page says organizers can automate emails as part of registration. Eventdex email is for event transactions such as confirmations, reminders and updates, not for promotional campaigns. The page does not list which emails or what timing options exist, so ask in a demo.
