Reducing Spam Emails populating Hubspot?

[SBaker12]

Is there a way to reduce spam emails from automatically populating HubSpot and then having to manually delete them? Maybe there is a feature where I may have to click on an email to manually enter them as a contact in Hubspot versus it being automatic. Please share your recommendations. Thank you.

Hi @SBaker12,

Form submissions automatically create contacts - this behavior cannot be changed. There isn't any way to approve contacts. There are however a few things you can do:

You can enable Google CAPTCHA on your forms: https://knowledge.hubspot.com/forms/prevent-spam-form-submissions#enable-captcha

You can manually block email providers if you can identify a pattern: https://knowledge.hubspot.com/forms/prevent-spam-form-submissions#block-specific-email-domains-or-fr...

You could include a hidden field in your form, assuming that especially bots would accidentally fill this – and then filter out contacts where the hidden field is filled. (This is also called a "honeypot".)

If there is any pattern in how contacts fill certain fields (e.g. within the message field, the email domain, first and last name), you can build an active contact list that finds these contacts and regularly delete contacts form the list. You would refine the criteria over time. https://knowledge.hubspot.com/lists/create-active-or-static-lists

Hope this helps!
