Hi @PatriciaH8969,
You could have a segment that's assigned to the same list as your sign up form that segments members of that list based on some additional criteria. Tags are a little more retroactive so they don't have an integration with signup forms.
Based on what you've shared so far the best option may be to create a sign up form to gather interested contacts, and then create a monthly newsletter with the upcoming classes for the month. It's not the most automated solution, but it does provide the most flexibility for both the content, and the send date. If you'd like a more automated/less content specific path, you could create an automation campaign that sends an email every 30 days reminding subscribers to sign up at your website. These emails would have to be more generic without specific class info, because subscribers will be joining at different times throughout the year. It may also take quite a bit of setup time at the beginning, and it should be noted that there are a maximum of 31 "steps" or emails in an automated series, so eventually some subscribers will "complete" the automated series.
Another solution already mentioned would be Lead Generation Landing Pages - These weren't really meant for recurring event registration, so as already mentioned you would have to create a new page for each event. They will give you a little more control over the "thank you page" that subscribers see after signing up, which will allow you to add a button to the page on your website that you'd like to redirect to. If they are already on your contact list it would still work, but it might be a good idea to create an individual list for each one in case you'd like to do any communication with people after the class, such as sending out a survey or providing a recording. Downsides to this approach is that they would not be embedded, you will just have a link for each form - on top of the lack of automation.
Lastly there are Event Campaigns . These are campaigns more catered to event registration. Potentially a good option if you need to accept payment for the events or provide a Zoom link, but they unfortunately don't have a recurring event option at this time so the set up may be a little cumbersome on a monthly basis.
I think the monthly newsletter with links back to your website for registration is a good way to go. Even though it isn't quite automated, they can be scheduled in advance and after the first set up the template will likely follow a similar format each month, so you would mostly be making a copy and changing dates/links. Happy to answer any more questions though!
