What's new in SendFox

Hey Sumo-lings,

Here's what we've shipped since June:

  • Smarter automations. Start one when someone gets a tag, add or remove tags along the way, and split people with yes/no branches (did they open, click, or have a tag?).
  • Contact tags. Tag people by hand, in bulk, or when they sign up, then email everyone with a tag.
  • Write your next email with AI. Paste a link to a post or video, or describe an idea, and SendFox drafts it.
  • A new email editor. Slash commands, columns and more fonts.
  • A report for every email. Opens, clicks, your top links, and who got it.
  • Teams. Invite teammates with their own login. No more shared passwords.
  • Unsubscribe from one list, not all. People pick which lists to leave instead of leaving you completely.
  • Moving from Kit? Import your subscribers straight into a SendFox list.
  • New forms and smart pages. Popups, slide-ins and sticky bars, plus themes and a live preview.
  • Skip a list when you send. Send to one list and leave out anyone on another.
  • Use SendFox from Claude. The SendFox MCP lets you add contacts and draft campaigns just by chatting.

Questions & reviews

AskSumo

Customers appreciate SendFox, praising its user-friendly interface, effective automation features, and unbeatable pricing at $29. The ability to schedule campaigns and grow lists with unlimited automations, Smart Pages, and forms is a standout. There are a couple of minor drawbacks, such as the absence of a full HTML editor in the Lifetime plan and the need for a paid newsletter ability in the Pro monthly plans, but these are just small bumps on the road. Weighing the raves against the occasional grumbles, SendFox is hitting the mark and is a solid buy for anyone looking to streamline their email marketing efforts. Plus, with a 60-day money-back guarantee, there's no reason not to give it a try!
