Mail server SMTP email send (rate) limit for popular web hosting providers
Why do you need to know your web host's SMTP email rate limit
If you run a web site and you plan to send out mass emails (for example, a newsletter),
it is advisable to send the emails using an authenticated SMTP mail server that matches the nameserver records for your own domain name.
This way, your outgoing emails will not trigger anti-spam filters set to identify phishing emails or spammers.
For example, if you run a web site at www.my-web-site.com, our advice is to send the emails from a SMTP server name that resolves to the same domain name (like smtp.my-web-site.com).
However, to prevent spam, many web host providers enforce email send rate limits to their customers.
The goal of this article is to show you the email send rate limit and options for most popular web host providers, such as GoDaddy, FastServers, HostWay, RackSpace, iPowerWeb and more.

Important note: Please do NOT take this information for granted, as your host provider can change its mail server policy without any prior notification.
It is always a good idea to contact your host provider and ask about the email send rate, before proceeding with a mass email campaign.
