Goal
LinkedIn does not provide a "Message everyone" button, making it difficult and time-consuming to reach event attendees before or after an event, especially for large groups. In this guide, you'll learn how to do just that.

Common problems and solutions
How can I message attendees for a large event with hundreds of people?
For larger events, you can use a LinkedIn automation tool (such as Phantom Buster) to send bulk messages automatically using personalized variables like name, job title, or company name.
What is the recommended daily limit for automated messaging?
To stay within safe limits and avoid account restriction, you should set your automation tool to a maximum of 20 messages per day.
How can I make my LinkedIn event follow-up messages more effective?
You can use webinar engagement data, such as CTA clicks, poll answers, chat engagement, and Q&A participation, to personalize your follow-ups. If you use this data, your outreach won't be a "cold" follow-up. Contrast is a webinar platform designed for HubSpot users. It captures engagement data (like polls, chat and CTA clicks) and automatically transfers it to HubSpot. This allows you to see exactly how an attendee interacted during the webinar so you can act on that data within your CRM.
