How to automate webinar follow-ups with AI: ConvertKit Review 2026
Short version: ConvertKit does the job well enough for most creators who run webinars and want to send AI‑assisted follow‑up emails without wrestling with a clunky automation builder. If you need deep CRM features or advanced lead scoring, look elsewhere.
I’ve been using ConvertKit for about eight months to handle post‑webinar sequences for a weekly live show. The price is $29 per month for up to 3,000 subscribers, which feels fair given the time I save on writing follow‑up copy.
Is ConvertKit worth $29/mo for webinar follow‑ups?
That’s the question I kept asking myself after the first month. The answer leans yes, but with caveats.
ConvertKit’s AI features live mostly in the email composer. When you start a new broadcast or automation email, a small sparkle icon appears. Clicking it opens a prompt box where you can ask the AI to draft a subject line, a preview text, or the body of a follow‑up email. The output is surprisingly readable if you give it a clear brief like “write a friendly thank‑you note to attendees who stayed until the end, include a link to the replay”.
The AI does not replace a human editor; it gives you a first draft that you still need to tweak for tone and brand voice. I’ve found it cuts my writing time from about twenty minutes per email to roughly eight minutes.
What I like most is the visual automation builder. You drag a “Subscribe to form” trigger, then add an “Email” node, then a “Delay” node, then another “Email” node. The canvas stays clean even when you have five or six steps. Compared to the spaghetti‑like workflows I’ve seen in older tools, this feels like a relief.
One concrete love: the ability to tag subscribers based on which webinar they attended. I run three different shows each month, and ConvertKit lets me apply a tag automatically when someone signs up for a specific event. Later I can send a targeted replay offer only to those tags. This segmentation has bumped my replay click‑through rate from 12% to about 18%.
Now for the gripe. The AI sometimes insists on inserting emojis even when I tell it not to. If I ask for a professional tone, the first draft still throws in a smiley or a clapping hands emoji. I have to delete them manually, which feels like a small but annoying extra step. It’s not a deal‑breaker, but it’s the kind of thing that makes you wonder if the model was trained on too many marketing newsletters.
Another annoyance is the lack of a built‑in webinar registration form. You have to embed an external form (like from Demio or Zoom) and then map the submitted data to ConvertKit via Zapier automations or the Make platform. If you’ve tried Zapier, you know what I mean — setting up the mapping takes longer than it should.
What breaks at scale?
ConvertKit works fine for a few thousand subscribers, but once you push past 10,000 the automation start to feel sluggish. The visual builder still loads, but the delay between dragging a node and seeing it appear can stretch to a couple of seconds. More importantly, the AI credit system becomes a bottleneck.
ConvertKit gives you a limited number of AI generations per month based on your plan. On the $29/mo tier you get 500 AI credits. Each email draft costs about five credits, so you can generate roughly 100 emails before you run out. For a creator who runs two webinars a week and wants to test multiple subject lines, that limit feels tight. You either upgrade to the $49/mo tier (which bumps credits to 1,500) or you start drafting manually again.
If you’re sending out dozens of follow‑up variations per week, you’ll hit the ceiling fast. That’s the point where I’d consider switching to a tool that bundles unlimited AI usage, like HubSpot’s AI assistant (though HubSpot’s pricing jumps dramatically).
