Here’s the bottom-line, per GetResponse:
- Emails have the best results within the 1st hour after delivery. This is when 23.63% of all emails are opened. But 24 hours after delivery, the average open rate is close to zero.
- Almost 40% of all messages are sent between 6 a.m. and noon. This can result in inbox clutter, and significantly decrease results for these emails.
- Messages sent in the morning and early afternoon have a better chance of being noticed and consequently achieve better results: up to 10.61% open ratio and up to 2.38% CTR.
- Subscribers’ top engagement times are 8 a.m. – 10 a.m. and 3 p.m.- 4 p.m. with up to 6.8% average open rates and CTR.
Of course, this all depends which time zone you’re optimizing for and that depends where your audience is located. For our U.S. clients, we typically use Eastern Time, but it’s interesting to note that GetResponse has a tool (Time Travel) that can schedule emails based on time zone segmentation.
