Best Day and Time to Cold Email?

Based on my 10 years of experience in cold emailing and marketing + as a recipient of hundreds of email, here's what generally works best:

Best Days:

• Tuesday and Thursday – consistently get higher open and reply rates.
• Wednesday is also a safe bet.

Avoid Mondays (people clear backlog) and Fridays (they're winding down).

Best Times:

• 8–10 AM (recipient's time zone) – Inbox is fresh, less clutter.
• 1–3 PM: Post-lunch, people often check emails again.

Avoid late evenings or weekends (unless you're emailing founders - they sometimes read emails on Sundays).
