Personalization such as including a recipient's first name or last name does not significantly improve open rates. - MailChimp (2007)

Providing localization, such as including a city name, does help improve open rates. - MailChimp (2007)

Repeating the exact same subject line for each newsletter accelerates the drop in open rates. While it is important to establish continuity and branding of the newsletter, ideally each new campaign should provide a clear indication in the subject line of what is inside this newsletter that is of interest. - MailChimp (2007)

The general rule of thumb in email marketing is to keep your subject line to 50 characters or less. Our analysis found this to generally be the rule. The exception was for highly targeted audiences where the reader apparently appreciated the additional information in the subject line. - MailChimp (2007)

As a best practice the From and Subject line should work in tandem. The From line should communicate who you are as the sender. As much as possible this entry should not change and should concisely convey who you are. - MailChimp (2007)

Within the category of promotional emails, the same basic rules apply. Keep the message straightforward and avoid using splashy promotional phrases, CAPS, or exclamation marks in your subject lines. Subject lines framed as questions can often perform better. - MailChimp (2007)
