Email marketing, as many of us know, can be a powerful, inexpensive method of reaching our most active potential or existing customers. It can boost not only our direct sales, but also our credibility and referrals.
One of the major benefits of email marketing is that email is free, but obviously this is the same reason why spam has become so popular and so frustrating. With spam comes spam filters and with spam filters comes the blocking of legitimate email.
In this article I’ll try and describe the basic steps that can help reduce the number of emails you send out that get blocked by spam filters — hopefully resulting in a more rewarding marketing effort.
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.

Our usual advice is that implementing sender authentication is a useful way of avoiding your email being incorrectly flagged as spam (i.e., a “false positive”). So you should implement rDNS, DKIM and SPF.
DKIM–DomainKeys Identified Mail–is an important standard for email sender authentication. It allows a recipient to verify that a message really does come from the sending domain that it claims to have come from. Senders publish a public key for their domain and then cryptographically sign their outgoing email, using the corresponding private key. Recipients can then verify the signature, typically as part of the spam filtering process.

What is a reverse PTR record?
PTR record or more appropriately a reverse PTR record is a process of resolving an IP address to its associated hostname. This is the exact opposite of the process of resolving a hostname to an IP address.
PTR is generally a concern for mail, as some mail servers will reject mail originating from IP's that don't have a valid PTR.
Example, when you ping a name mail.somedomain.com it will get resolved to the ip address using the DNS to something like 192.168.1.5
Email spam, also known as junk email or unsolicited bulk email
A junk mail folder is a virtual inbox for storing ads and often unsolicited electronic mail.
Be sure to check it regularly and every few days you should check your spam folder to make sure no important email messages have accidentally been identified as spam.
Programs within e-mail generally include customization options to move unwelcome messages to a junk mail folder automatically, but often this mail needs to be manually moved to the folder after reaching an in-box.
When e-mail from an undesirable source comes through, typically there is a block list for logging the sender’s e-mail address or extension, subject field, or content keywords and having like messages sent directly to the junk mail folder.
