Sidekick is a free service that gives you email superpowers with contact insights, email tracking, and email scheduling



Sidekick by HubSpot is an email tracking app that sends real-time notifications every time someone clicks on or opens your emails.

The app shows you when they viewed the email, how many times they viewed it, where they were when they opened it and from what device.

Sidekick also includes recipient profiles directly within your inbox.

These profiles show your contact’s professional history, their address, mutual contacts, and email history.

With the ability to schedule future emails, Sidekick helps to ensure you don’t forget to send emails or that your emails go out at a specific date and time.

Sidekick integrates with HubSpot, Salesforce, Gmail, Outlook, Chrome and Safari.
