Historically, Tuesday and Thursday are the highest-converting days for B2B cold outreach. Mondays are typically consumed by internal meetings and clearing weekend backlog, making prospects highly likely to mass-delete cold pitches. Friday afternoons suffer from “weekend checkout,” meaning your email will sit unread until Monday morning, where it is again likely to be deleted.

Absolutely. C-Suite executives and Founders usually check their emails on their mobile devices very early in the morning (6:00 AM – 7:30 AM) or late on Sunday evenings before their week begins. Conversely, mid-level managers and individual contributors are more likely to engage with emails during the mid-morning (9:00 AM – 11:00 AM) or the post-lunch afternoon lull (1:30 PM – 3:30 PM).

Always schedule emails based on the prospect’s local timezone. If you are operating on EST and want to hit a California-based executive at 8:00 AM their time, you must schedule the email for 11:00 AM EST. Sending an email at 8:00 AM EST means it hits their inbox at 5:00 AM PST, burying it under hours of automated newsletters by the time they wake up.

Perfect timing cannot fix bad data. If you are sending emails to outdated, unverified, or catch-all addresses, your bounce rate will spike. When this happens, email providers (like Google and Microsoft) will silently route your future emails to the spam folder, meaning your prospects never even see them. To maximize open rates, you must combine optimal timing with 100% verified data from a provider like Accurate List.
