Frequently asked questions
What is Killer Email?
Killer Email is an AI inbox triage app for Gmail and Outlook, made by Jozi Firecracker Factory LLC.
It quarantines promotions, social notifications and other noise, and turns the mail that matters into one action list: Today, Next Week and Later.
Who is Killer Email for?
Killer Email is for anyone running life across more than one Gmail or Outlook account: busy parents juggling school, family and work email; freelancers and consultants with client threads in several inboxes; people with a side hustle on top of a day job; solo business owners like realtors, contractors and online shop owners whose leads and invoices get buried under vendor mail; job seekers who can't afford to miss a recruiter reply; people who help manage a family member's inbox; and anyone who freezes at a full inbox and just wants one short list of what to do.
Is it safe to connect Gmail or Outlook to Killer Email?
Yes. You connect through Google's or Microsoft's own sign-in, so we never see your password, and you can revoke access anytime. Killer Email is built so it can't send, delete or move your mail; those actions are blocked on our servers. Every permission we request is listed on our Security page.
Does Killer Email read my full emails?
No. Sorting uses the sender, subject, date and the short preview your provider already shows, from your inbox only. It never reads attachments, junk or archived mail. The one exception: when you press Add to calendar, it reads that single email to find the date and time, and doesn't keep it.
Can Killer Email delete or send my email?
No. Killer Email never deletes or sends your email. Replies are saved as drafts in the account the email came from, only when you choose, and you send them yourself.
What happens to quarantined email?
It stays exactly where it was in Gmail or Outlook. Quarantine is just a view inside Killer Email. One tap rescues anything, and Killer Email learns that sender matters. Mail is only marked read when you tap Done or Archive, or confirm Clear Quarantine.
Does Killer Email work with Outlook, Yahoo or iCloud?
Killer Email supports Gmail and Outlook. Yahoo and iCloud are not supported.
How many email accounts can I connect?
Solo includes 1 Gmail or Outlook account and Pro includes up to 10 accounts — any mix of Gmail and Outlook.
How much does Killer Email cost?
Solo costs $5 per month and Pro costs $9 per month, and the first 7 days are free.
Cancel in two taps. Cancel before the trial ends and you pay nothing. When the paid period ends, every inbox is disconnected and your Killer Email account is erased; your actual email is never touched.
Is my email used to train AI?
No. Your email is never used to train AI models, and requests to our AI provider are sent with storage turned off. Details are in our Privacy Policy.
How is Killer Email different from Gmail's tabs and filters?
Gmail's tabs group mail by type; Killer Email also turns what's left into a ranked action list with a one-line summary of what you owe.
It works across up to 10 accounts — any mix of Gmail and Outlook — and can draft replies and add calendar blocks when you ask.
Compare Killer Email vs SaneBox, Killer Email vs Shortwave, and Killer Email vs Gmail tabs and Gemini.
How do I disconnect or delete my data?
Remove an account in the app and its access is revoked and its data erased. Cancel your plan and the same happens for every account, plus your Killer Email account is erased, when your paid period ends. You can also check access in your Google or Microsoft account settings.
