Best time to send cold emails by industry. Tested across 40 clients

After managing cold email for 40+ clients across different industries, I have actual data on optimal send times by vertical. The generic "send Tuesday at 9 AM" advice is too simplistic.
SaaS/Tech (targeting developers, engineers): Best: Tuesday-Thursday, 10 AM-12 PM. Developers check email later in the morning. Monday mornings are sprint planning. Avoid Friday entirely.
Marketing/Agency (targeting CMOs, marketing directors): Best: Tuesday-Wednesday, 8-9 AM. Marketing people are early email checkers. Thursday-Friday they are in campaign review mode.
Real Estate (targeting property owners, investors): Best: Monday-Tuesday, 7-8 AM. Real estate professionals start early. Midweek they are at showings and hard to reach by email.
Financial Services (targeting CFOs, controllers): Best: Wednesday-Thursday, 9-10 AM. Early week is month-end or quarter-end crunch. Give them a couple days to settle in.
Healthcare (targeting administrators, practice managers): Best: Tuesday-Thursday, 11 AM-1 PM. Morning is patient-facing. Lunch hour is when admin email gets checked.
E-commerce (targeting D2C brand owners): Best: Monday, 9-10 AM. They plan their week Monday morning. By midweek they are focused on operations.
These are averages from thousands of campaigns. Your specific ICP might differ, so always A/B test timing within these windows. But this gives you a strong starting point instead of guessing.

the real estate timing insight is interesting. I sell to property managers and can confirm Monday morning works way better than midweek. they're actually at their desks planning the week before showings start

40 clients worth of data backing this up is way more convincing than the usual anecdotal 'i tested on my 3 inboxes and Tuesday works best' posts. saving this as a reference for every new campaign launch

what about recruiting emails to specific roles? I target engineers who probably check email at different times than the marketing directors you mentioned. any data on optimal times by job function rather than industry?

does anyone test lunch hour sends? 12-1pm seems like a time when people are scrolling through their inbox casually and might be more receptive than first thing in the morning when they're triaging
