Features

Email tracking and engagement data

Track email opens and link clicks, then use engagement patterns to see when a message is most likely to get attention.

Real-time notifications

Get open, click, reply, and status alerts on desktop and mobile so you can respond at the right time.

Per-recipient visibility

See which recipient opened a message, where they were, and which device they used when a message goes out to multiple people.

Tailored sending with mail merge

Use message templates and mail merge to personalize bulk outreach with contact data from Apple/Google/Outlook Contacts, HubSpot, Salesforce, or CSV files.

Inbox collaboration tools

Assign messages, exchange notes, share tasks, and view collaborator status in a shared inbox to reduce duplicate work.

Signatures and workflow automation

Create and share email signatures, add marketing elements, and apply automation rules for recurring inbox workflows.

Use cases

  • Sales and outreach follow-up

    Track opens, clicks, and recipient behavior to decide whether to follow up, wait, or adjust the message approach.

  • Shared inbox coordination

    Assign emails, add notes, and see collaborator status in a shared inbox so team members do not duplicate work.

  • Personalized campaigns and sequence sends

    Build personalized bulk emails with templates and mail merge fields drawn from contacts, CRM records, or CSV files.

  • Email signature management

    Share and control branded signatures across a team, then add calls to action or other marketing elements to standardize outgoing mail.

  • Inbox workflow automation

    Use automation rules to apply signatures, tags, notes, and tasks when events such as sends, opens, clicks, or draft creation occur.
