Email filtering for public meeting request buttons

    Hello Earl,

    Thank you for sharing this idea! You are not alone, this is a popular request. We recently released single use links in our Chrome extension to help users solve this problem. However, I can see that this does not solve the problem for you since you are sharing your Calendly events via embed.

    While I don't have a target date on when we will offer blocking specific email addresses, I can share your suggestions with the team to discuss further.

    Hi there,

    I am a big fan of Calendly. I am using the Pro account and loving it. Thanks so much for the zoom integration. I use it so much now, it's exactly what I needed.

    I want to make a request for another feature and explain the use case of why I need it. Hopefully there is already a solution for this!

    Currently, on my website there is a form to Request a Demo. When the user submits the form, they are redirected to a thank you page. Within seconds, they receive an email that includes my Calendly link. This current method provides some measure of "protection" from fake submissions, because they can only reach my calendar if they have a real email. However, we still get tons of "Bill Gates", "John Does", "Steve Jobs"... etc. Spammers basically. However it is slightly mitigated because they can only get to my calendar link within the body of the confirmation email. 

    However in order to reduce these steps and to get more meetings, I want to embed the link directly into my website (such as here:

    For example, when the Demo forms are submitted, I want them to immediately see my calendar and be able to book right away...without having to open an email, click a link, redirect back to the browser, etc. HOWEVER, I'm very hesitant to do this because if I enable the embed, any person could have unrestricted access to my calendar and in effect cause a "denial of service" by filling my calendar with meetings that they never show up for. I am doing 5-10 sales meetings per day, and my calendar time is sensitive and valuable to me. So far we have reduced pointless meetings slightly,  but still I am worried that if I embed the calendar onto our webpage without validation, it would ruin an entire day to have even 1-2 hrs of fraud meetings. People do this all the time and it's really hard to tell that a person put a dummy meeting if there is no email validation. 

    So, I want to ask if Calendly already has the feature to validate an email address (similar to a captcha)? Or maybe there is a way (as Earl described) to require that users submit a corporate email? I am not sure if Calendly offers this feature in your own widget, or I need to add this feature onto my own web form itself as a preliminary method of validation?

    I'd love to hear what you think and discuss in more detail.

    Thanks :)
