Mixmax works inside Gmail so nothing falls through the cracks. Founded in 2014, it's used by people who handle their own outreach — founders, agency owners, recruiters, consultants, fundraisers and small business owners — and by the teams they work with. When you send an email, Mixmax keeps track of it. You can see when someone opens it or clicks a link. If they don't reply, Mixmax reminds you, or sends your next email for you. By default, follow-ups stop the moment the person writes back, so nobody gets another nudge after they've answered.
