Introdution

At this moment, AWS SES service is the best affordable price and high-quality service to sending (and receiving) programmatic emails. But, one day your account could be suspended without notice, and that takes a big effort of requesting support to get it back to work.

So it’s good to prevent that siatuation happens by watching your Bounces Rate and Complaints Rate. One way to resolve problem when your rates being too-high than allowance, is send a big amount of dummy emails to your blackhole email address.

Example

These is your send statistics :

  • Deliveries : 2000
  • Bounces : 180 ==> Bounces Rate : 180 / 2000 = 9%
  • Complaints : 30 ==> Complaints Rate : 30 / 2000 = 1.5%

Meaning :

  • Bounces : when your email didn’t send to existed email address (maybe your user type wrong or input fake one), we can pre-validate email before sending by using some email validator library or services like fast-email-validator
  • Complaints : when your receiver mark your email as SPAM :( Poor you !!!

Solution

AWS SES rules :

  • Bounces Rate : 5% => So you have to send more (180 / 4%) - 2000 = 2500 emails to reduce Bounces Rate to 4%
  • Complaints Rate : 0.1% => So you have to send more (30 / 0.07%) - 2000 = 40857 emails to reduce Complaints Rate to 0.07%

==> Number emails send = max(2500, 40857) = 40857 emails

SPAM YOURSELF 40857 EMAILS !!! 😂
