Learn how to create and use Add to Calendar links for email campaigns. One-click calendar invites that work with Google, Outlook, Apple Calendar, and more. No .ics files needed.
Getting people to actually show up to your event starts long before the day arrives. One of the most effective (and underused) tactics is including Add to Calendar links for email, a simple, one-click solution that puts your event directly on your attendees’ calendars the moment they read your message.
In this guide, you’ll learn why Add to Calendar links outperform traditional .ics files, how to create them with AddEvent, and how to embed them in your email marketing campaigns to drive higher attendance.
Add to Calendar links (sometimes called ATC links or calendar event links) are clickable URLs embedded in an email that instantly add an event to a recipient’s preferred calendar app. No file downloads. No manual imports. Just one click, and the event appears on their calendar.
Unlike traditional .ics (iCalendar) files, Add to Calendar links for email are:
Whether you’re promoting a webinar, product launch, conference, or sales call, embedding an Add to Calendar link in your email is one of the simplest ways to reduce no-shows.
Before Add to Calendar links became widely available, marketers relied on .ics files: iCalendar attachments that recipients would download, open, and manually import into their calendar app. It sounds straightforward, but in practice, it’s anything but.
Adding an event via a .ics file can require anywhere from four to seven steps:
If the file is zipped, add two more steps. Every extra click is an opportunity to lose a potential attendee.
For iPhone users who don’t use Apple Calendar as their default, the frustration is even greater. The phone automatically opens .ics files in Apple Calendar, regardless of the user’s preferred app.
Even when recipients successfully open a .ics file, the event may not display correctly. Common problems include:
Testing a single .ics file across Google Calendar, Apple Calendar, and Outlook is a time-consuming process, and even then, you can’t guarantee a consistent experience for every recipient.
When something goes wrong with a .ics file (and it often does), you risk losing the attendee entirely before they’ve even added your event to their calendar. That’s a problem you can eliminate completely with Add to Calendar links.
Switching from .ics attachments to Add to Calendar links isn’t just more convenient. It’s measurably more effective.
One Click Is All It Takes
Instead of walking recipients through a multi-step import process, Add to Calendar links do the work for them. Click the link, and the event is added. That’s it.
AddEvent customers have reported an average 30% increase in event attendance after switching to Add to Calendar links. Fewer barriers to adding an event mean fewer reasons not to show up.
Add to Calendar links work seamlessly across all major calendar platforms:
No matter what device or email client your subscribers use, the experience is consistent.
When you create an Add to Calendar link with AddEvent, you control exactly what information gets added to the attendee’s calendar:
Everything a recipient needs to attend, right on their calendar from day one.
Creating add to calendar links for emails (or add to calendar buttons for your website and landing pages) is easy. With AddEvent, you can automatically generate unique event links for each event and share them in your email campaigns, event pages, or social media posts. Whenever someone clicks the link, the event is seamlessly added to their preferred calendar platform.
If you have multiple events to share, you can also share a calendar link for your entire events calendar to not overwhelm your customer base with numerous event invitations or links.
Here’s a step-by-step walkthrough.

.ics files, or iCalendar files, are a common format for sharing events, but they come with significant drawbacks, including manual import requirements, time zone issues, end-user issues, and more.
Unfortunately, no. Compatibility issues are a significant drawback of .ics files. Each calendar platform — Google Calendar, Apple Calendar, and Outlook Calendar — interprets .ics files differently, leading to event display and functionality inconsistencies.
To make sure that guests show up to your next event, include an add to calendar link in your email campaigns. With that, subscribers can add your events to their own calendars, helping them avoid calendar conflicts and allowing them to set up their own reminders and maximize the chance of attending your event.
Add to calendar links (ATC links), sometimes called calendar event links, are a simple and efficient alternative to .ics files, offering a streamlined way to add events to your calendar with just a single click — no downloads or manual imports needed.
Log in to your AddEvent account and create a new event and enable RSVPs. Go to your Event Details Page & find the Add to Calendar Link section. Copy the code provided and paste into your email template and viola! You are all set with your calendar links using AddEvent as your calendar link generator.
Create your event in AddEvent, copy the generated HTML code from the Sharing Tools section, and paste it into the HTML editor of your email template. Each platform has a slightly different interface, and AddEvent provides platform-specific documentation for HubSpot, Mailchimp, ActiveCampaign, Marketo, and Salesforce Marketing Cloud.
