Key Features

1. Multiple senders can send concurrently

   You can add any number of different sender accounts to send at the same time, which not only improves sending efficiency but also bypasses the daily sending limits of single accounts. In theory, with enough sender accounts, you can send massive volumes without restriction.

2. Customizable email content templates

   Email content can be entered directly or composed from predefined modules.

   Templates are customizable and can be saved to a template library for easy reuse.

   Templates are defined in HTML format, and the application provides a visual editor that is friendly to both beginners and advanced users, giving templates unlimited possibilities.

3. Unlimited variables — each email can be unique

   Supports data variables and random variables. These variables can be referenced in templates, and during sending the program automatically replaces them with real values so the same template can produce personalized content for different recipients.

4. Multi-threaded concurrent sending — 100k+ daily possible

   Each sender uses its own thread for sending. The more senders you have, the faster the sending speed. With enough sender accounts, sending 100,000 emails per day is feasible.

5. Retry on failure

   With multiple sender accounts, if sender A fails to send, sender B will continue sending. If only one sender is available, failed items can be resent from the send history.

6. Custom randomization algorithms

   When multiple senders and templates exist, the program intelligently selects them randomly to improve deliverability.

7. Daily sending limit per mailbox supported

8. CC and BCC supported

   Support for copying multiple recipients to specific addresses or copying different emails to different recipients.

9. Email read tracking

   Track when emails are opened to enable more accurate marketing analytics.

10. Unsubscribe support

    For marketing emails, include an unsubscribe option to better comply with local regulations, improve user experience, protect sender reputation, reduce complaints, and enhance marketing effectiveness.

11. Permission management

    Organization administrators can view and manage all sub-users' data and settings for centralized control.

12. Built-in scraping capabilities to support market expansion

13. Outlook OAuth2 sending supported

    Outlook supports sending via RefreshToken or account password.
