Email Warmup by Boxward Product Information and Latest Updates (2025)

Hey Product Hunt! 👋 Sam from Boxward here. Excited to share our email warmup tool with you! If your cold emails are going to peoples’ spam folders instead of their main inboxes, your outreach efforts are wasted. If your emails land in spam, you’ll see a drastically lower open and reply rate, generating fewer leads and sales. So, over the last 50 years (give or take!), we set out to see how we could better ensure our outreach emails would land in the inbox. And today we’re excited to hunt Boxward - an email warmup tool that helps improve your email deliverability so that your emails land in the inbox every time.

Awesome, congrats on the launch! Warming up emails is such an important part of cold outreach and it's nice to have more innovative options in this space.

Do you recommend keeping a slow warmup running even during cold campaigns to monitor deliverability?

@amfraine Thanks! And yes, it's definitely important to keep warmup active on any email that you're using for cold outreach. Boxward has a "Maintain" algorithm that is the perfect fit for an email that already has good deliverability and you just want to be sure to keep it in good standing.

this looks awesome? What's the recommended minimum warmup period? 1 week? 2 weeks? a month?

@ryan_wardell1 The average time we recommend for a brand new email is 4 weeks. And in that time, you shouldn’t be using that email for anything else. Some people do warm-up for 2 weeks, others 2 months. But, 4 weeks is good. If your email has already been in use for awhile, you can put it on a Maintain warmup routine, which is designed to keep your deliverability good once you're warmed up and sending your outreach emails.
