The concept of a single best day and time to send an email is misleading. Instead, marketers should vary send times throughout the week to reach different segments of their audience. The key metric is the aggregate number of unique individuals engaged weekly, not the performance of a single blast.

Recent data indicates a significant shift in optimal email marketing send times. Contrary to the long-held belief in early morning sends, emails delivered between 8:00 and 8:30 AM are now generating a 12% performance lift compared to the traditional 6:00 to 8:00 AM window.

Contrary to belief, Fridays are a peak day for webinar registration as professionals focus on self-improvement. Similarly, sending long-form emails on Sunday mornings sees high click-through rates as executives catch up on reading without workplace distractions.

Instead of optimizing for a single "best" send time, marketers should vary sending days and times (e.g., evenings, weekends). This strategy acknowledges that different people within your database interact with email at different times, maximizing overall reach and engagement across your entire list.

Sending all your automated emails at a predictable time, like 9 AM, trains your audience to ignore them, turning them into "wallpaper." To break this pattern and make automations feel less robotic, vary the send times significantly, even using unconventional hours like 8 PM.

A massive study by OmniSend found that Friday, once considered the worst day for email marketing, is now one of the top two best days, along with Tuesday. Friday also has the highest send volume of the week, indicating high user engagement and challenging old marketing assumptions.

The 10-day period from January 20-30 is a prime time for email campaigns. Professionals are past the holiday slump and newly motivated for the year, making them highly receptive to demo requests, content downloads, and purchases before the next holiday marketing cycle begins.

The idea of a single best time to send an email is outdated. Instead, measure success by the weekly aggregate of unique individuals opening your emails. Sending at various days and times hits different audience segments, maximizing your total reach over time.

Over 80% of marketers send emails on the hour, flooding inboxes in the first 10 minutes. By scheduling campaigns for a non-standard time, like 8:07 AM instead of 8:00 AM, you avoid this clutter and can increase open rates by around 15%.
