How EmailUnlimited Gets Your Email Delivered |
|
|
Delivering email to large lists of contacts can be quite a challenge, especially
if you have a large number of recipients who maintain their accounts with one of
the major ISPs.
ISPs like AOL, Yahoo, Hotmail or Gmail are flooded with billions of email
messages every day. Most of them are junk email, so these outlets have developed
very complex mechanisms of filtering emails that makes it hard to get into their
users' inboxes.
Here are some of the mechanisms that are used to filter incoming email:
|
- Monitoring IP addresses and giving them a priority status
- Graylisting mechanisms that reject emails periodicallly
- Domainkey verification
- Feedback mechanisms help identify spam sources
- Content filtering mechanisms
|
Establishing and maintaining high delivery rates is not an easy task.
EmailUnlimited has a number of special mechanisms to deal with those hurdles.
|
|
Getting Along With Graylisting Mechanisms |
For example, when you send more than 100 emails to Yahoo or Hotmail, they will
reject your email and tell you to 'come back later'. The poorer your sender
reputation the more often your emails will be rejected on a temporary basis, and
the longer it will take to deliver your emails.
EmailUnlimited will retry the delivery to graylisted records up to 10 times.
Furthermore, it will slow down the delivery in order to maintain a certain
priority status and get more of your emails emails delivered. Yes, the delivery
will take a bit more time, however, success rates will be higher, too.

Avoiding Invalid Email Addresses |
Repeatedly sending email to non-existing email addresses at a certain ISP is a
way to ruin your IP reputation. If you try to send an email to
aaa@yahoo.com several times, Yahoo.com will
ultimately get feed-up of your emails, no surprise.
Here is how EmailUnlimited helps:
When you send an email to an invalid contact that returns a 'user unknown'
status, EmailUnlimited will automatically add it do a global do-not-email list
that contains unknown email addresses from all our senders. It is a great way to
protect your delivery reputation with the big ISPs.

|
Domainkey Verification |
Domainkey verification is also a big issue: Several large ISPs will outright
reject the delivery of your emails if they do not contain any domain key
verification. To be precise: they will not directly reject the delivery...they
will tell you that they have accepted your emails...and then plainly delete it.
It never arrives.
For that reason, EmailUnlimited will automatically add a verified domain key
signature to any email that is targeted to an ISP that watches for domain key
verification, such as Google or Yahoo.

Feedback Loop Mechanisms |
Probably you have seen these little 'This is spam' buttons on web-based email
accounts.
When people receive an email from you and click on that little button, of
course, it is not a good thing, as it marks your email as spam, which means that
more of your other emails are likely to hit the junk mail folder.
There is some good news, however: EmailUnlimited will automatically add people
who hit the "This is spam" button to your do-not-email list. This prevents
people from repeatedly complaining about emails and protects your delivery
reputation. |

It is also up to you |
Simply said: if you send unsolcited bulk email with phoney offers to everybody
and their dog, all our knowledge and technology will not help you get your email
delivered. Spamming gets everybody into trouble and will kill the delivery
reputation of all users of our system, and for that reason, we will remove any
spamming user from our system.
If you have a large list of email contacts at a specific ISP and have delivery
problems, we will also be glad to contact that ISP on your behalf and get that
delivery issue solved. |
