To optimize php.ini for email marketing, focus on these key settings:
SMTP: This setting specifies the SMTP server to use for sending emails. Example: SMTP = smtp.your-email-provider.com sendmail_path: If you're using Sendmail, specify its path here. Example: sendmail_path = /usr/sbin/sendmail -t -i max_execution_time: Ensure the script has enough time to execute, especially for large email campaigns. Example: max_execution_time = 300 memory_limit: Allocate enough memory for the script to handle bulk email operations. Example: memory_limit = 128M
