Hi Kerry,
You can do this via automation. Just use the form as an entry point followed by the email sequence. Here's a short clip22 for reference.
Now please also double check your email template, if that's a starting point template, we cannot use it yet for sequence. That's only available for broadcast emails. For the sequence email, you can definitely use all the templates under CLASSIC templates.
If you have further questions, I recommend you email help@convertkit.com12 to take a look at your account.
Thank you!
