Sending Frequency Doesn’t Affect Unsubscribe Rates
You might think that sending an email newsletter every day would annoy recipients and lead them to unsubscribe. However, according to a survey*, the unsubscribe rate remains the same whether you send emails once a month or 30 times. Even the open and click rates don’t change significantly.
This suggests that sending more frequently can actually improve results.
Click Rates Aren’t Affected by Email Length
You might assume that longer, more detailed emails would result in higher click rates (e.g., for inquiries or “view details”), but in reality, the length of the email doesn’t affect the click rate.
Images Don’t Boost Click Rates
Having many attractive images might seem like it would grab more attention and increase click rates, but it doesn’t actually make a difference.
Considering all of this, sending a brief email newsletter daily appears to be more effective than sending a lengthy and detailed one monthly.
Quantity seems to outweigh quality.
It appears that sending frequent, simple emails without worrying about “overdoing it” may be the best approach.
