how often should i send email marketing?

when it comes to email marketing, quality is better than quantity.  excessively frequent emails will annoy customers and make them more likely to unsubscribe.  

start with 2-3 emails sent each month and increase or decrease the amount sent based on customer feedback. remain consistent with when you send emails, such as every other Monday at midnight.  this will make it easier for customers to expect your updates and will make them more likely to read and share them.
