MailerMailer's latest Email Marketing Metrics Report (pdf) takes a look at open and clickthrough rates, the best days of the week to send emails and how personalisation and subject lines can affect open rates.
It finds that emails with subject lines of 35 characters or less are 28% more likely to be opened, and that open rates have declined overall so far this year.
US email marketing company MailerMailer released its Email Marketing Metrics Report this week, revealing practices to help businesses increase returns from their email campaigns.
Key factors highlighted in the report include the use of shorter subject lines, personalisation of emails, and targeted, well-managed lists. Campaigns using these strategies achieved higher then average open and click rates.
