I am sending out ~30k email messages.
Each message will have slightly different content.
I have read that using the php mail() function is not a good idea for Mass Mailing.
What are the pro’s and con’s of using the inbuilt mail() function and the pro’s and con’s of using a Mass Mailer such as Swiftmailer.
With particular focus on the fact that it is not sending the exact same message to 30k addresses,
Instead it is sending slightly personalized messages.
Outsource it or spend a lot of time with a library. SwiftMailer is a a good choice if you decide to go with a library.
Don’t loop with a mail() 🙂
