AddEvent

What it is

AddEvent is calendar-based event engagement software that helps organizations increase event attendance and reduce no-shows by making events easy to save, share, subscribe to, update and manage across users' calendar apps. Rather than building a ticketing system or full event management platform, AddEvent specializes in the moment when someone wants to save an event: turning a link into a calendar entry, collecting RSVPs without friction, and letting attendees update their calendars when events change. Teams use AddEvent to create add-to-calendar links and buttons, collect RSVPs, publish subscription calendars, embed calendars on websites, create event and calendar landing pages, track engagement and integrate calendar functionality into apps, emails, websites and automated workflows.

What you build and how

At the core is the add-to-calendar experience. You share beautiful add-to-calendar links in emails, on websites or social channels. Recipients click, and the event is saved to their calendar app (Google Calendar, Outlook, Apple Calendar, etc.) automatically. Buttons on your website do the same: visitors click to subscribe to your calendar, and every event on it syncs to their device. The company's pitch is that when the event lives in the user's own calendar, attendance goes up and no-shows go down.

Event landing pages are built with no-code design templates that drive conversions. There is no developer or design team needed. The templates are designed for simplicity and speed, highlighting key event details and including built-in calls to action. You can build a single event page or a subscription calendar page where users browse multiple events and click to add any to their calendar. Landing pages are hosted by AddEvent and customizable: the templates let you apply your brand colors and fonts, and the company's guide suggests a hero image or background video to set the tone.

The landing page builder uses a low-code visual interface so you see changes immediately. Pages include sections for event name and tagline, date and time with timezone, location or event type (online, in-person), and a main call-to-action button. Below that, you can add speaker bios, photos, agenda highlights, testimonials or past event statistics.

Online RSVPs are collected on customizable registration pages. You design the form, add questions to collect information you need, and reminders and follow-up emails are automatically sent after submission. The form can be embedded on your website or shared as a standalone page.

For multi-event series, a subscription calendar lets attendees subscribe once and get all upcoming events. Each calendar has a landing page, an embeddable widget you can add to your website, and an add-to-calendar link you can share in emails. When you add a new event to the subscription calendar, the company says subscribers' devices update automatically.

Email campaigns can use dynamic add-to-calendar links that update for each recipient. You embed the links in email marketing campaigns and specify parameters that customize the event for each unique recipient. The company says this works with email campaign tools such as Mailchimp, Marketo, Salesforce, Constant Contact and HubSpot.

An embeddable calendar widget shows your upcoming events on your website. Visitors can browse, click and instantly add any event to their calendar. You can even add a countdown timer to build excitement.

Integrations with Zapier connect AddEvent to 6,000 plus other apps and services. A powerful API supports custom integrations. The site says the tools work with website builders and CMSs including Wix, Webflow, Squarespace and WordPress, and with email marketing platforms and CRMs including Mailchimp, HubSpot, ActiveCampaign, Salesforce Marketing Cloud and Braze.

The product description also lists engagement tracking among the things teams use it for.

Evidence from the pages

The homepage lists the offer by channel: Add to Calendar links in emails, a landing page AddEvent creates and hosts for each event, an event added to your website "in seconds" with "no coding experience required", online RSVPs with automatic reminder and follow-up emails, subscription calendars, an upcoming-events list with an optional countdown timer, an embeddable calendar widget, and Dynamic Add to Calendar links for email campaigns. The RSVP page lets the organizer choose what information to collect and add extra questions.

Integrations are stated plainly: the Zapier integration connects with "6,000+ other apps and services", there is an API for custom needs, and the site names Wix, Webflow, Squarespace and WordPress on the website side. Pricing, documentation, updates and a security and analytics page are linked from the navigation.

Social proof comes from review sites, quoted on the homepage. It shows 50+ reviews at 4.4 on Trustpilot, 35+ at 4.7 on Capterra and 50+ at 4.5 on G2. Quoted users praise reliable, easy setup and a support team that sends videos to walk them through problems. These are the company's selected testimonials.

The company's own guide is explicit about scope. It says AddEvent "is not a meeting scheduling app, ticketing marketplace, webinar hosting platform, CRM, email service provider, or replacement for Google Calendar, Outlook, or Apple Calendar", and that it works alongside those tools. It calls itself a fit when you want a hosted, embeddable calendar experience without building or maintaining calendar infrastructure yourself, and says it manages compatibility with calendar providers, email clients, browsers, mobile operating systems, time zones and recurring events.

Who it suits and who it does not

AddEvent suits a team that already has an audience and a place to reach it, such as a newsletter, a website or a social following, and wants more of them to actually show up. Marketing teams sending campaign invitations can use dynamic add-to-calendar links to customize the event for each recipient. Organizers of a webinar series, a recurring class or a venue calendar get subscription calendars and an embeddable calendar. Small organizers who want a landing page and an RSVP list without developers can start from the templates, and teams already on Mailchimp, HubSpot or Zapier can connect them.

The caveat is scope, and the company states it. AddEvent is not a ticketing marketplace, a meeting scheduler, a webinar host or a CRM, so paid tickets, one-to-one appointment booking and contact management belong in other tools. A conference with exhibitors and on-site check-in needs a fuller event platform. AddEvent is strongest as the front door that gets people to save the date and say they are coming.
