These are the sending limits for emails on LINUX shared hosting:
You can send up to 100 email messages per hour using Webmail, 19 emails per minute using PHP, and 9 emails/minute using SMTP (Thunderbird - Outlook). There is also a daily limit of 10000 emails applied to PHP and SMTP sending collectively.
These limits cannot be changed, and exceeding these limits may result in suspension of the email service. To set your own limits and send more emails, feel free to check out our VPS packages: https://intelplanet.com/vps
Mass mailing is not recommended in our email services – instead, I would suggest going for email marketing service such as MailChimp. I’m sure you will find the best service for mass mailing ????
