Improved deliverability and smarter email detection in Hunter Campaigns

We’ve made several important improvements to Hunter Campaigns to help you achieve better deliverability, keep your inbox cleaner, and focus on the conversations that matter most.

Full-text campaigns for better deliverability

Campaigns now automatically adapt based on how you compose your emails:

  • Full-text campaigns are now the default when you don’t add formatting (such as bold, links, or lists).
    • These emails are sent as plain text, giving them a more personal look and feel.
    • Plain text messages are less likely to trigger spam filters and typically achieve higher deliverability.
  • Formatted campaigns remain available when you use styling or links.
    • The editor now displays a notice reminding you that plain text usually performs better.
    • You can easily switch back to plain text at any time with the formatting toggle.

Smarter unsubscribe handling

Hunter now adapts the unsubscribe sentence automatically based on your email type:

  • Plain text emails: “If you don’t want to hear from me again, please let me know.”
  • Formatted emails: “If you don’t want to receive more emails, click here.”

Both versions are applied automatically, so you don’t have to make any changes manually.


Automatic unsubscribe and out-of-office detection

Hunter now automatically detects and processes unsubscribe requests and out-of-office replies, saving you time and keeping your campaigns cleaner.

  • Messages containing “unsubscribe” within the first 100 characters are automatically added to the Unsubscriptions section.
  • Common out-of-office phrases (such as “out of the office,” “away from my desk,” “currently unavailable,” “on vacation,” or “I will respond upon my return”) are also recognized.
  • These emails are visible directly in your Inbox, giving you the option to manually pause scheduled follow-ups or keep them as they are.

This automation helps you stay compliant, avoid follow-ups to unavailable contacts, and maintain a strong sender reputation.


Why this matters

These improvements help you:

  • Get better inbox placement and maintain strong deliverability.
  • Save time by handling unsubscribes and out-of-office replies automatically.
  • Keep your outreach natural and focused on real conversations.

These improvements are live for all Hunter Campaigns users. You’ll see the formatting indicator, unsubscribe notice, and automatic detection directly in your Campaign Editor and Inbox.
