A Direct Marketing Agency - Helping Brands Acquire and Retain Customers

The size of your email list may determine the best day to send your campaigns according to a recent study.
The study broke lists out into four sizes:
Micro: under 5,000 names
Small: 5,000 - 24,999 names
Midsize: 25,000 - 99,999 names
Large: over 100,000 names

For large lists, the best mail dates are still Monday through Wednesday. The bigger the list, the less efficient it is with lower read and click-through rates. However, one exception that some mailers can use to their advantage is that B2C lists over 200,000 were most read when emailed on Saturdays. This is most likely due to this being a day when consumers are making shopping decisions.

Large lists can perform better when broken into smaller segments based on what is known about the customers. Use dynamic data to treat each segment differently as the more relevant the message, the more reads and clicks.

Other findings were that Micro mailings do best on weekends, although they perform significantly higher than other size lists on any day of the week. Again, relevance is the key factor.

Small lists perform best on Fridays, and midsize mailings are most productive on Mondays and Fridays.

The size of your list does matter! Once you determine the size, you can schedule your mailing dates to get the most out of your campaigns. And remember, relevance will always improve the bottom line.
