Answer 1

I have a mailing of 30000 emails. I am looking for a free solution to be able to send email to all the contain in this mailing list.

I don't think there is any SMTP service for free for this amount of emails.

Is it possible to code in PHP the solution ? Is it easier to do with another coding langages ?

This is not a programming or programming language issue, this is SMTP service issue.

Is there any free software which would give you this possibility ?

Again, this is not a software issue, this is a service issue

You need to get some SMTP email send out service for this.

If you have option for cron job then :

Add one column in your email database. say email_sent with type smallint It will add value as 0 by default.

Now create a php script which will send email. In this script, select three (with limit clause) rows everytime with condition where email_sent='0' After sending email to email-ids in these three rows, update email_sent='0' to email_sent='1' in that rows.

Now set your cronjob to run per minute. So you can send 180 emails per hour. Generally shared hosting allows 200 / 250 emails per hour. (** of course as your table contains 30,000 rows, it will take around 6 days to send emails to all but as you needed free option, then some compromise is also needed )

Now second part, create another php script for cronjob to run every day / weekly etc. which will reset email_sent='1' to email_sent='0' in whole database table. So you can send new emails again with same php scripts.
