Send your webinar follow-up within 24 hours, and send three different emails, not one. Attendees who asked a question get a personal answer. Attendees who watched quietly get the recording and one useful extra. People who registered and did not show up get the recording with a shorter, lighter message. Sending one blast to everyone wastes the best signal a webinar produces: who actually showed up and what they did.

A webinar leaves you with a registration list and an attendance report, and the gap between them is where the follow-up should start. Before the event, check what your webinar tool lets you export: who joined, how long they stayed, and the questions they typed. Zoom Webinars, for one, fills in its Attendee and Q&A reports only after the webinar ends, so pull them that afternoon, not the night before. This page assumes you hosted the webinar. If you were a guest speaker, ask the host before the event to share the registrant list with you, or have them send your email, since the list belongs to them.

The webinar in this example

Caleb Fontaine runs a payroll consultancy and hosted a 45-minute webinar called "Payroll Mistakes in Your First Year" for new restaurant owners. Say 140 people registered, 52 attended live, 9 stayed to the end of the Q&A, and 3 typed specific questions. Rina Torres asked how to stop chasing timesheets every pay period. Dev Malhotra attended 20 minutes and left. Leah Park registered and did not join. All names, numbers and the firm are invented for illustration.

Sort by what people did, then write

Use three groups. Group 1: asked a question in chat or Q&A. Group 2: attended part or all, never typed anything; mark the ones who stayed to the end, since they are the warmest of the group. Group 3: registered, did not attend. In Caleb's case, group 1 is three people and deserves personal emails. Group 2 can get a templated email with a mail merge in Gmail for names. Group 3 gets the same recording with different wording. The reason to split is simple: someone who typed a question has told you their problem, and an email that ignores it is a wasted conversation.

Template 1: you asked a question (send within 4 hours if you can)

Answer the question in the email itself, and do not just promise to cover it later. The answer is the reason they will read it.

Subject: Your timesheet question from today

Hi Rina,

You asked how to stop chasing paper timesheets from your servers every pay period. We ran out of time, so here is the short answer: move clock-ins onto your point-of-sale system or a time-clock app, and lock the week's hours at a fixed time, say Monday at noon. Payroll then runs from one locked report instead of a stack of paper.

The recording is here: [link]. Your question comes up at about the 38 minute mark, just before we ran out of time.

If you would like to talk it through for your restaurant, I have 20 minutes open Thursday at 11 or Friday at 3.

Why it works: it gives the answer first, points to the exact minute in the recording, and offers a conversation without pressing for one. A reader who got a real answer is the likeliest to book the call.

If the honest answer is "it depends", say what it depends on in one line and offer the call instead: "That one turns on your state's rules, so I would rather look at your setup than guess." That is still an answer, and it gives the call a clear purpose.

Template 2: you attended and said nothing

These people showed up, which is a real signal. Do not assume more than that. The email gives them the recording, one extra resource they did not get live, and a single easy question.

Subject: Slides and recording: payroll mistakes in your first year

Hi Dev,

Thanks for joining this morning. The recording and slides are here: [link]. I also added a one-page checklist of the six mistakes, because several people asked for something to print.

One question, only if it is useful to you: what part of payroll worries you most right now? A word or two is plenty, and I will point you to the right section.

Caleb

If the platform shows that Dev left after 20 minutes, do not mention it. It reads as surveillance. Use the information privately: someone who left just before the timesheet section might want that segment sent on its own.

Template 3: you registered and did not attend

Never scold. People miss webinars for ordinary reasons, and some register only to get the recording. Make that easy.

Subject: The recording you asked for

Hi Leah,

We missed you this morning. The recording is here: [link], and it is 45 minutes, with the questions at the end. If you are short on time, the section on timesheets starts at the 22 minute mark.

Caleb

That is the whole email. A no-show has told you less than an attendee has, so the message stays this short.

Recording, slides and one extra: what goes in the email

Link the recording rather than attaching it. Gmail's help center sets a 25 MB attachment limit for personal accounts and swaps anything larger for a Google Drive link, so a link you control is tidier than a file that may not arrive as a file. Attach or link the slides as a PDF, and add one extra the live audience did not get: a checklist, a template or a calculator. Do not attach a price list or a proposal to a webinar follow-up. The attendee agreed to learn something, and the first email after should deliver that. The sales step belongs in the second email, a few days later, and should be a short offer to talk, not a catalog.

The second email, on day four or five

On day four or five, send group 1 and group 2 a short second note: "Did the recording help? If you would like a second pair of eyes on your payroll setup, I do a free 20 minute review for people who joined." Offer something specific and bounded. Send it once. Our guide to following up after a sales meeting covers the same rhythm for one-to-one contacts.

Legal note on emailing registrants

The Federal Trade Commission's CAN-SPAM compliance guide sorts email by its primary purpose. A message that only delivers something the person already agreed to receive, such as the recording of a webinar they registered for, may count as transactional, and the guide says transactional messages are exempt from most of the law's provisions. Add an offer, like the call in Template 1 or the free review in the day-five note, and the email becomes commercial. A commercial email needs your physical postal address and a working opt-out honored within 10 business days, and that holds for business readers too. Registrants in the EU or UK fall under other consent rules, so check those before you write. This is general information, not legal advice.

Webinar follow-up subject lines by group

  • Group 1: Your timesheet question from today
  • Group 2: Slides and recording: payroll mistakes in your first year
  • Group 3: The recording you asked for
  • Day five: Did the recording help?

Name the webinar topic, not the word "webinar". For more on what makes people open a message, see follow-up email subject lines.

Which registrants deserve a phone call

Phone group 1 people who answered your email with a yes, or who work at a company that fits your best customer. Do not phone people in groups 2 and 3 just because they registered or watched. The one exception: if someone from a company you have wanted to reach for a while stayed for all 45 minutes, a call is fair; mention the webinar in the first sentence and keep it to a single question.

Rocketship can send follow-ups like these from your own Gmail and stop when someone replies, and its Conversations feature finds public posts on Reddit, Quora and LinkedIn where people ask about the subject you teach, then drafts the reply. A 7-day trial will show you how it handles a list of registrants.
