What Instantly is for
Instantly is one of 23 tools in our AI Email Assistants list. Cold email outreach at scale with AI.
Email assistants triage your inbox, draft replies and summarize long threads. Some are complete email clients while others plug into Gmail or Outlook, which matters if you do not want to switch apps.
What to check before choosing Instantly
- Reply drafts that actually sound like you after some use.
- Support for your email provider, shared inboxes and mobile.
- What access the app needs, and how message data is stored.
These tools read sensitive mail. Check the security documentation and your company's policy first, and keep reviewing drafts instead of allowing automatic sends.
