  • Avoid sending emails to strangers without their permission, to minimize the chances of getting flagged as a spammer.
  • Minimize the spam complaints by simply giving your recipients an option to unsubscribe.
  • Minimize the use of mass mailing tools. Instead you can use a cold email automation tool, which mimics human like email sending behavior and doesn’t get detected by spam filters.
