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.

To test if subscribers are actually reading your full email, hide a specific, fun instruction in the middle of the copy (e.g., "If you see this, reply with this word"). The replies you receive serve as a clear indicator of deep engagement beyond just opens or clicks.

An unengaged segment skews your metrics, making you misinterpret what's working. You might change effective content or offers based on artificially low open/click rates. Cleaning your list provides accurate data for making sound strategic choices.

Many marketing platforms may inadvertently count clicks on the 'unsubscribe' link as part of the overall click-through rate. Manually ensure these are excluded from your reporting to get an accurate measure of positive engagement, as high unsubscribes should not inflate your success metrics.

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.

The idea of a single best time to send an email is outdated.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.

Despite claims that Apple's privacy changes and bots have made them irrelevant, open rates remain a valuable leading indicator for email performance. Marketers who dismiss them are ignoring a crucial signal of audience engagement and list health. These metrics are provided by platforms and should be monitored.

Every email campaign has a different role. An event follow-up's goal might be to generate replies, making that the key metric. A nurture email aims for value delivery, while a sales email aims for demos. Judge each campaign by its intended outcome, not by universal vanity metrics.

Avoid sending all your automated communications at standard, predictable times like 9 a.m. By scheduling some automations to go out at unconventional hours, such as 8:07 p.m., you can cut through the noise and prevent your messages from becoming "wallpaper" that customers are conditioned to ignore.
