Send personalized emails at scale
Send personalized, tracked mass emails and follow-up sequences in Gmail.

Need to send mass personalized emails?
Use mail merge to send tailored messages at scale with automatic follow-ups.
Personalize messages for higher response rates
Send personalized individual emails to hundreds of recipients in just a few clicks. Address recipients by first name, reference their company, or include different types of data from your pipeline.

Prevent that faux pas with smart email alerts
Never send a cold outbound message to a recipient your team has already emailed. Streak alerts you if your team has ever emailed with a recipient and shows you a timeline of your team's communication history.

Built in email tracking to see who’s opened your email
Receive a notification when any email is viewed, and see exactly when each one was last opened and the total number of views, so you know who to follow up with next.

Schedule and automate follow-ups at the right time
Schedule follow-up emails to increase engagement if recipients don't reply to your first message. When a recipient replies, they'll be excluded from the remaining messages so you can respond to them personally.

See how your emails are performing in one view
See engagement and performance data for your campaigns, like the number of recipients who viewed and replied. Track link clicks and compare which mail merges perform better.

Target your recipients with organized lists
Want to send a follow-up to specific recipients? Import your contacts into a pipeline to keep them organized. Filter and sort them based on any criteria and send your next mail merge to a targeted list.

Customize your outreach with advanced controls
Configure your mail merge follow-ups to start a new thread, pause on replies, ignore out-of-office and vacation messages, send as a marketing sequence, or add an unsubscribe link.
