If you are going to send emais to 3000++ users. Will you still use php mail function? I heard, it was not secured enough. How do I send a secured blast emails? I dont want to use third-party software if possible.
If you are going to send blast emails in php, what method or functions you will use in php?? (Tried google “advanced sending email in php”, but could not find a good answer)
Oh ya, heard this thing called phpmailer, is it good? Should I replace that with my current mail function? (Its free)
Lastly, what are the things you need prepare to send thousands over emails?
The best method I’ve found for large lists is to use PEAR Mail in conjunction with Mail_Queue. Essentially, the messages get queued for delivery (stored as records in a MySQL database) and then a cron job runs periodically throughout the night to send them in manageable batches (using php CLI).
