If you’re just getting into mailing or are still unsure about how the technical side of mailing works, hopefully the information below will help you. Some of this information has been quoted directly from the email providers and other parts I have found out over the years.

Sending limits:

Gmail: 100 emails per account, per message (this is why you need to use tokens), per 24 hours. More than this gets you a temporary block. Note: This is only when using external applications to send (e.g. Outlook, Thunderbird, Mail Mascot etc).

When using the web client, the email limit is increased to 500.

Hotmail: 100 emails per account, per 24 hours. Important: The limit of sending with Hotmail accounts is strictly influenced by age of account. New accounts will almost always bring up captchas if you are using other applications to send through. However, once your account passes the 3-4 month mark, you will stop receiving captchas and should be able to send in excess of 100.

Yahoo: No more than 100 emails or recipients per hour. It is also not uncommon for accounts to experience blockages pretty quickly.

Comcast: 1000 emails per day.

It is also important to comment on how your IP influences sending. Typically if you are located somewhere in the indoasia and pacific areas, your IP may be shared between a number of people and may have been flagged by email providers. This particularly only matters when you send through an email client and even then you can use proxies.

That’s right proxies. From what I found if you double the sending limits, those become the ‘max messages allowed to be sent from IP’. After this, your IP may get added to a blacklist, which will send most of your mail to junk. This is why it is important to either operate a VPN (Virtual Private Network) or use legitimate Socks mailing supported proxies. Apart from your encrypting your network usage, they will also allow you to bypass the set sending limits. However, it’s crucial that the proxies you use are reliable otherwise you will encounter two things.

1. Slow speeds and lots of failed messages.
2. Your emails hitting junk.

Using a VPS or (Dedicated Server)

A virtual private server (‘VPS’) has now become a nice way to send through, although it does have its pros and cons which I will discuss below.

Pros

No sending limits
Full control over your sending
Faster sending (depending on the quality of your server)

Cons

May fall into a spam trap once too many emails start originating from the IP
A lower inbox percentage
A little more timely to set up and configure correctly with a VPN.

I know many people want to buy bullet proof servers, located god knows where for anonymity, but if you’re just going to be sending your typical CPA offers and what not, then a regular server will be alright, as long as you keep it legal.

Hostgator provide pretty decent servers (VPS servers). They will set everything up for cheaper than the industry average. And, if you buy cPanel with your server, getting it ready for mailing is super simple.

cPanel account home > email accounts > (add your account) > more info > configure email client (to find smtp details).

This is the simple run down. Ultimately, it would be good to have a different IP for each domain you have under your server.

SMTP Details

Gmail

Hostname: smtp.gmail.com
Port: 465
Authentication: SSL

Hotmail

Hostname: smtp.live.com
Port: 587 or 25
Authentication: TLS

Yahoo

Hostname: smtp.mail.yahoo.com
Port: 465
Authentication: SSL

Headers

Email headers are the ‘behind the scenes’ information that come attached to an email. Some of them you may recognize, some you might not. Here are a few. At times using the right headers may help you bypass spam filters.

Name
To
Subject
From
Date
CC (Carbon Copy)
BCC (Blind Carbon Copy)
Reply-To
Priority – This can be used to influence speed and delivery and also to draw attention to the email in your recipient’s email client
X-Mailer – What email client created the email (e.g. Mail Mascot, Outlook, Gmail etc)
DomainKey Signature – Getting registered with DomainKeys is great for your inboxing. It tells your recipient’s email client, what email provider has sent out the email. Typically, email providers that are given a DomainKeys Signature are considered reliable.
X-MS-Has-Attach – Identifies whether or not the email has an attachment present.
X-Accept-Language – Tells the server which language to use in a reply
Content-Type – Explains how to view the email, and which format it is (e.g. text, HTML, audio etc)
X-Originating-IP – The IP address of the computer that sent the email
X-Spam Score – How likely is it that this email is spam. The higher the number, the more likely it is spam and the more likely it will be placed in the junk folder.

That’s all for now, I know I haven’t covered everything but this should give you a start into understanding the technicalities of email marketing.
