What every webinar invitation needs
Most invitations fail in the same way: they describe the webinar instead of the reader's problem. Nobody registers for "a discussion of trends in procurement". People register for "how to cut your renewal costs before the budget meeting".
- The promise, in one line. What will they know or be able to do after 45 minutes? Put it in the subject line or the first sentence.
- Who's speaking, and why them. One line each. A practitioner beats a title.
- The date and time in the reader's zone, or two zones if your list spans regions. Add the length: people decide by whether it fits.
- One link. To register, near the top, and again at the end. Not three buttons and a social bar.
- What happens if they can't come. "Register and we'll send you the recording" catches the people who are interested but busy.
- A real sender. A name people recognize, with a reply address that reaches someone.
Leave out the agenda with timings, the paragraph about your company and the long speaker bios. Put those on the event page, where the person who's already curious will read them.
Write one invitation per audience
The same webinar needs different invitations for people who've never heard of you, for customers, and for people you know personally. The promise stays the same; the reason to care changes. A customer wants to know it's relevant to what they already use. A cold reader wants to know why they should trust you with an hour. Someone you know wants to hear it from you, in your words.
If you only have time for one, write the personal one. A short note from a named person to someone they know tends to outperform any designed email, because it doesn't look like marketing.
Five templates
Change everything in brackets. Then read each aloud: if a sentence sounds like a press release, cut it.
The cold invite, for a list or a newsletter
Subject: How to [the outcome], [day] at [time]
Hi [first name], On [day, date] at [time, zone], [speaker], [one-line credential], is showing how to [the outcome]. In 45 minutes you'll see: - [specific thing one] - [specific thing two] - [specific thing three] It's free and online. Register here: [link] Can't make it live? Register anyway and you'll get the recording. [your name] [your role]
The personal note, to someone you know
Subject: Thought of you for this
Hi [first name], We're running a short session on [the topic] on [day] at [time]. Given what you said about [their situation], I think the part on [one specific thing] would be useful to you. Here's the link if you'd like to come: [link] No pressure at all, and if it's not the right time I'm happy to send you the recording. [your name]
The customer invite
Subject: For [product] customers: [the outcome]
Hi [first name], You're one of the teams using [product] for [use case], so I wanted you to hear about this first. On [day] at [time], [speaker] will walk through [the outcome], using [a feature or setup they'll recognise]. There'll be 15 minutes for your questions. Register here: [link] If there's something you'd like us to cover, reply and tell me. We'll build the session around the answers. [your name]
Forward to a colleague
Subject: Fwd: [webinar title]
Hi [first name], Thanks for registering for [webinar title] on [day]. People often tell us a colleague would get as much from it as they would. If someone comes to mind, forward them this link and they can register in one step: [their own share link] See you on the [date]. [your name]
Last call, two days before
Subject: Thursday: [the outcome] (last call)
Hi [first name], A quick note in case this slipped by: [speaker] is showing how to [the outcome] this [day] at [time]. [Number] people have registered so far, and the questions they've sent in are about [common theme], so that's where we'll spend most of the time. Register here: [link] [your name]
When to send them
For a free webinar, most of the registrations arrive close to the date, so a two-to-three-week campaign is usually enough. Send the first invitation about two weeks before, a second to people who haven't registered about a week before, and the last call two days before. Send the personal notes in between, a few each day, rather than all at once.
Don't send the same email twice to the whole list. People who registered after the first one shouldn't get the second. Remove them before each send, or use a tool that does it for you.
Subject lines that get read
The subject line has one job: tell the reader what they'd get, and when. A few patterns that work:
- The outcome and the time: "How to cut onboarding to a week, Thursday 1pm".
- A question from the audience: "Should you raise prices before renewal?"
- The speaker, when they're the draw: "Priya Shah on pricing for usage-based products".
- Plain and personal, for a note: "Thought of you for this".
Avoid "You're invited!" on its own. Every webinar invitation says that, so it tells the reader nothing.
Make sure it arrives
An invitation to a large list is bulk mail, and the big inbox providers have rules for it. Google's email sender guidelines require every sender to Gmail to set up SPF or DKIM and keep spam complaints low, and senders of more than 5,000 messages a day must also have DMARC, and marketing messages must support one-click unsubscribe. If you send from your own mailing tool, check those are in place before the campaign, not after the first batch bounces.
Personal notes avoid most of this: they're one-to-one email from your own mailbox, to people who know you.
How to tell if your invitations worked
Count registrations from each invitation, not opens. Give each email its own link (one for the newsletter, one for the customer email, one for the personal notes), and see how many people registered through each. Then check how many of them came. Opens are unreliable, because some mail apps open messages by themselves, and you don't need to watch individual readers to learn which email filled the room. Our guide to tracking registration sources covers the details.
Doing this in Programmable Talk
Your webinar stays on Zoom, Luma or wherever it runs. For the personal notes, paste the people you know (email, name, company) and each gets a personal link that opens the event page addressed to them, where one tap registers them. Opening the link never registers anyone, so a mail scanner can't sign someone up by accident. You can send the invitations from Talk, with replies going to you, or download the links and send them from your own mailbox. Every registrant gets their own share link for the forward-to-a-colleague email, and each invitation, link and code counts as its own way in, so the Promote tab shows which one filled the room. Reminders then go by themselves; see webinar reminder emails.
