Blacklists and Whitelists
Sending your newsletter from a new IP address is like trying to obtain credit. The bank (in this case the ISP) will give you a little credit
upfront however will scale up or down depending on the complaint levels over time.
New accounts usually experience erratic deliverability for the first few months until a solid reputation can be
established with their new IP and "From" address. Best practice includes adding a reminder note in the newsletter to "whitelist us".
Deliverability
1. A completed transmission means that the newsletter was successfully accepted and let in by the ISP that hosts the user's email box.
2. Once the newsletter is let in, it's up to the ISP as to where it sends it next.
It can be put into the user's inbox if it's considered clean by their spam filter software, or maybe it's put into a spam box if they tag it as potential spam.
3. After the ISP has put the campaign in the inbox or spam box, the next step is the user accessing the newsletter.
If the user has personal spam software on their computer and using Outook, when they click the send/receive button to download email,
their spam filter may be tighter then then ISP's and will tag it and put it in the spam box.
Newsletter Bounces
We will attempt to send to a soft bounce 3 times.
After 3 soft bounces, the status will then become a Hard Bounce.
A Soft Bounce occurs when a mail server recognizes the email address but can't deliver the message for some reason.
- the mailbox is full
- their server is down
- their server breaks the connection
- the user abandoned the mailbox
A Hard Bounce can occur when a mail server won't recognize the mailbox as valid or existing and therefore it won't allow entry.
Spam Filters
Most ISP's and exchange servers utilize the top of the industry software called Spam Assassin to wash all email.
It's updated almost daily and every email that comes in is given a "score".
The average score is 5, meaning all email taged 5 or higher will be considered spam.
Some ISP's keep it tighter and set the limit at 3. Various things that can effect the score include:
- Spam suspected words or phrases.
- New IP from the sender of the newsletter.
- Subject line choice.
- Too many click through links.
- All image newsletter.
- Too many spam complaints from other users receiving from the sender.
- HTML code that isn't optimized for email rendering.
Testing
Our expert team tests all newsletters before we send them.
1. We run all content and code through a "Spam Assassin Validator" to assure it will pass the filters.
2. We send tests to several email seed accounts to assure it renders correctly and gets delivered successfully:
Outlook, Outlook Express, AOL, Gmail, Hotmail and Yahoo.
