Every webinar platform shows you the same flattering number first: registrants. It’s the number in the big font on the dashboard, and it’s also the number that lies to you most. The real number — who actually joined — usually lands somewhere between a third and half of it, and by the time you’re looking at the post-event report, it’s too late to do anything about the gap.
the confirmation email isn’t a reminder
Most registration flows send exactly one message: a confirmation, the second someone signs up. That email does its job — it confirms — and then it sits in an inbox for two weeks getting buried under everything else that person subscribed to. A single message sent at the moment of lowest intent (they just clicked a button, they haven’t blocked the time yet) is not a nudge sequence. It’s a receipt.
The invitees who show up aren’t the ones who read your confirmation email closely. They’re the ones whose calendar politely interrupted them twenty minutes before start time.
a calendar invite beats an inbox
This is the whole mechanism behind nudgt, and it’s worth explaining plainly: the moment someone registers, we put your session directly on their calendar — not a link to add it, the actual invite — and then we keep nudging over email and text on their own lead times, right up to start time. The last nudge typically lands closer to "now" than any confirmation email ever will, because it’s timed against the session, not against the signup.
If you run recurring sessions — a weekly office hours, a standing demo slot — the same mechanic applies every week without you rebuilding anything. See how it’s set up for webinar hosts specifically.
the part that actually protects your show rate
Reminders decay in usefulness the further they sit from the moment that matters. A reminder sent 5 minutes before start time is worth more than one sent 5 days before, but you need both — the early one for the calendar block, the late one for the "oh right, that’s now" nudge as they’re mid-task on something else. That’s why nudgt runs up to five nudges per campaign across email and SMS, each with its own lead time, instead of one blast that has to somehow work for everyone.
what this isn’t
It isn’t a mass-email blast tool, and it isn’t a paid-ads retargeting campaign either — both of those cost you again every time you want someone’s attention: a per-impression auction on one side, a per-contact monthly fee on the other. A calendar invite costs a fraction of a cent to place once, and every native reminder that follows is free, because it’s the invitee’s own device doing the reminding, not another message fighting for space in a crowded inbox.
If your sessions are less "everyone logs in from a laptop" and more "everyone walks through a door," the mechanism is identical — just pointed at an address instead of a join link. That’s the whole story in our post on filling the room for in-person events.
the version that requires nothing new to learn
You’re not adopting a second inbox or a new sending identity. Every invite and every nudge goes out through the SMTP account you already send from — Gmail, Outlook, whatever you’re on — and through your own SMS provider if you’re using text nudges. Nothing pools with other customers, so your domain’s reputation stays entirely yours.
