The webinar form is the friendliest looking consent trap in WordPress. One short form, name and email, a promising title, and behind it a CRM workflow that adds the registrant to a newsletter, a nurture sequence, and sometimes a partner's list, none of which the form mentioned.
Registrants are not subscribers who happen to attend an event. Untangling those two identities in the form, and in the tools behind it, is the whole job.
What registration actually covers
Registering is agreement to the communications the event itself requires: confirmation, a calendar hold, reminders, the joining link, and a follow up containing the recording or materials promised at signup. That is the deal the registrant understood.
It does not extend to a weekly newsletter, product campaigns, or a sponsor's list. If the follow up sequence turns into general marketing after the recording email, it has walked past the registration's scope, however the CRM labels the contact.
Co hosted events multiply the question
When a partner co hosts, the form must say who receives the registration data and for what. A logo beside yours on the landing page is not disclosure. Registrants deserve a sentence naming the parties they are agreeing to hear from.
Each party's use is its own consent problem. Your partner's right to market to registrants cannot ride on your form unless the form actually said so, in words a registrant could read before submitting.
Building the form in WordPress
Keep the required fields to what the event needs, add marketing as a separate unticked checkbox with plain wording, and make sure the form plugin records the checkbox state and the wording version with each entry. Test a full submission and inspect the stored record, not just the notification email.
Then follow the data: check what the webinar platform, the CRM, and the email tool each received. Integrations routinely sync every registrant into every list by default. The form can be perfect and the plumbing still wrong.
After the event: the honest follow up
Send what was promised: the recording, the slides, the offer explicitly trailed at the event if there was one. Then stop, for everyone who did not choose marketing. Their attendance was not a first date with your newsletter.
For those who did opt in, the first marketing email should still feel connected to the event they chose. Consent quality shows in complaint rates; a webinar list that complains is usually a list that never agreed to be one.

Frequently asked questions
Can I add webinar registrants to my newsletter automatically?
Not on the strength of registration alone. Registration covers event communications. Newsletter membership needs its own clear, unticked choice at signup, or a separate invitation afterwards that people can accept or ignore without affecting their registration.
What event emails can I send without marketing consent?
The messages the event needs to function: confirmation, reminders, joining details, changes, and the promised recording or materials. Keep them factual and event bound. The moment an email's main purpose becomes promoting other products, it has become marketing.
How do I handle co host data sharing on the form?
Name the co host and what they will receive and use, in plain text near the form, before submission. If the partner will market to registrants, that needs to be part of the choice the registrant makes, not a surprise in their inbox.
What records should the form store?
Timestamp, the form and wording version, the checkbox state for marketing, and which tools the data flowed to. Store it where you can retrieve it per person. A complaint about a webinar signup is answered with that record or not at all.
