Email Marketing: bounce management and bulk mails

[Sofia]

A self-hosted community has over 300,000 users registered over the years. I assume that at least 30% of email addresses are no more valid. It means I must manage e-mail bounces to proceed with bulk mails. I am going to switch from Google to Amazon SES/SNS. I have found two solutions:

• https://www.deschutesdesigngroup.com/portfolio-item/aws-simple-email-service-with-bounce-management/
• https://ipb.silvesterwebdesigns.com/file/9-mail-bouncer/

Do you have experience with one or another? Which one would you recommend recognizing, marking and excluding bounced email addresses from the bulk mail recipients in IPS?

Mail Bouncer by Silvesterwebdesigns / stoo2000 is the standard one used by most IPS communities.  

The one by Deschutes Design Group / Jon Erickson is newer. I don't have any experience with the file, but I like him as a developer.
