Interpretation
Think of your email like a tiny storefront on a crowded smartphone: with mobile driving about 41.6 percent of opens, iPhone and Gmail dominating, Apple Mail Privacy Protection inflating Apple opens toward 100 percent and leaving reliable open tracking to roughly half your list, a single broken image or poor mobile rendering can cut engagement by more than 20 percent and prompt up to 70 percent of users to delete within three seconds, so prioritize responsive, dark-mode and accessibility-ready designs, use AMP or plain text strategically, and stop treating open rates as gospel.

Timing, Frequency & Cadence
- 1Tuesday is often cited as the best day with an open rate of roughly 18.3%
- 2Weekends typically have the lowest open rates averaging around 17%

- 4Sending 1 email per week yields the highest open rate average per email
- 5Emails sent at 4 PM report a secondary spike in open rates for B2C
- 6Sending more than 5 emails a week causes open rates to drop significantly to under 15%
- 7Thursday is the second-best day for open rates typically matching Tuesday within 0.5%
- 823% of opens happen within 60 minutes of delivery
- 9Open rates drop to less than 1% after 24 hours of delivery
- 10Holiday emails see a spike in volume but often a drop in open rates due to fatigue
- 11Mid-month campaigns (10th-20th) often show steady open rates compared to end-of-month
- 12Subscribers who receive daily emails have a lower engagement rate than weekly subscribers
- 13Local time optimization can improve open rates by 2-5%
- 14Friday open rates are approximately 18.9% usually lower than mid-week
- 15The highest click-to-open ratios often occur at 6 PM despite lower volume
- 16Sending frequency optimization algorithms can boost opens by 10-15%
- 17B2B open rates peak earlier in the week while B2C holds into the weekend

- 19Sending 2-3 emails a month results in a specific open rate sweet spot for e-commerce
- 20Open rates for monthly newsletters are generally higher per email than weekly blasts
Interpretation
Treat subscribers like punctual guests who dislike nagging; send midweek on Tuesday or Thursday around 10 AM for B2B, expect a 4 PM bump for B2C and a 6 PM click-to-open peak, favor weekly or a couple of messages per month because daily sends or more than five a week push opens below 15 percent, optimize by local time and by send-frequency algorithms to lift opens 10 to 15 percent, and move fast since 23 percent of opens occur within an hour while under one percent occur after 24 hours, meaning holiday volume spikes often just add to fatigue rather than engagement.
