Use the ‘Add-To-Calendar’ Button to Supercharge Event/Webinar Attendance

I learn a lot about growth marketing from Appcues and one of their emails inspired this short article. I had to test the ‘Add to Calendar’ button on my own webinar invite and it increased attendees from an average of 38 to 52 in the last webinar.
That is a 50% jump in attendees.

Pains me so much when I host a webinar with way too few attendees.

If you use events or webinars as a conversion mechanism, always remember to use the ‘’Add to Calendar’’ Widget at the bottom of your email or CTA.

This can supercharge event/webinar attendance by 50%.

As some users add to their calendar, say Gmail, Outlook, Yahoo, iCalendar etc, aside from your reminder email, the user gets a prompt from their mobile calendar app. That increases their chance of joining the webinar directly from their calendar app.

How do you add the ‘’Add to Calendar’’ widget to your email?

I’m sure autoresponders like Klaviyo have that feature, but what if you do not use Klaviyo? You can use third-party services like:

https://www.addevent.com/

https://add.eventable.com/

https://www.litmus.com/

Add yours

The problem with these third-party services is that they’re too pricey! They have a free tier, but this limits the button calls to a fairly low number especially if you have a fairly large event/webinar.

Any FREE Alternative?

Yes. This brings us to an open-source ‘’Add to Calendar’’ button script built by Jens Kuerschner.

Rather than paying for this service, I highly recommend you use Jens’ open source project as it gives a better experience for free.

Some cool features in Jen’s project:

Simple and convenient integration of one or multiple buttons — configure them directly within the HTML code.

Optimized UX (for desktop and mobile) — adjustable.

Beautiful UI (the best combined from experts around the world).

Up-to-date integration of all popular calendars: Google Calendar, Yahoo Calendar, Microsoft 365 (and Outlook).

Automatically generated iCal/ICS files (for all other calendars, like Apple).

Timed and all-day events.

Translatable labels and dynamic.

Support for SEO-friendly schema.org markup as an alternative to the default structure.

Well documented code, to easily understand the processes.

The project now lives within its GitHub repository at https://github.com/jekuer/add-to-calendar-button.

You can download it there — or fork it if you know what this means (your developer can help)

Take a look at the Demo: https://jekuer.github.io/add-to-calendar-button/

The project was Product of the day on Product Hunt on November 13, 2021.

Just like me, give this a try and let us know if you observed a considerable jump in attendees.
