There are two types of blacklists that will effect your operation. They are IP blacklists and URI blacklists. One of them lists possible SPAMing IP addresses and the other lists possible URI's associated with SPAMing.
Different blacklists have different listing policies. While some collect and list IPs of mail servers that send to some "trap" email addresses others might list dynamicly assigned IP addesses, such as ADSL subscribes. There are many variations. You can find a list of blacklists on http://www.blalert.com/dnsbls and details on how they work.
You could also use a monitoring service like http://www.blalert.com to monitor your IPs if they are listed on any of the blacklists.
A bit of both. If a domain is caught as a constant spammer (definitely something to avoid!) you'll end up on the blacklist. Spammers will also consistently use up IPs (including those they hijack) so key IPs are also blocked. Best to use mail services as a result - MailChimp is good and free up to a number of emails. Depends how many you're sending, but if you're trying to send out millions of emails, you a) probably have the money for it or b) probably are spamming, and should stop.
I am reasonably specific this will be an actually bad concept for many reasons. Here are a few of them:.
1) To start with each of your e-mails will be massive. A lot of mail servers will just reject your message for size if not anything else. Any attachment is encoded using MIME or BASE64 which makes it even larger than the initial.
2) The majority of mail servers are configured to decline mass big messages. It is extremely uncommon that non-bulk senders would need to send out basically same video to numerous recipients simultaneously and the logic behind those filters is very affordable, so you could anticipate your message to be rejected a lot more frequently than regular.
3) The greatest concern is that most email clients are set up NOT to render any rich material other than plain text. They will accept text, fonts and possibly some vibrant and italic fonts, but many of them do not render CSS, Javascript, Video or even images. A great deal of mail clients are set up not to render them by default and it shows gaps with an "x" mark in them, so most of the time individuals will not even understand that there ought to be a video in there. All that planning and setup and most of your clients will not even learn about it.
The best and simplest pointer I would provide is host your video somewhere. Youtube or Amazon S3 for example and only include a small IMAGE of the video playing in the player with a small play button and always include a regular HTML link in plain text under it. It must urge people to click it.
In this case anyone who has images rendered, will see an excellent image of gamer with a play button, he will click the image and will immediately go to your website where the video autoplays as soon as possible, so there is no difficult sensations, you guaranteed a video ... Video was delivered.
Anyone who has no images rendered, will merely see a hole with a link under it and will be able to click the link in plain text to be taken the exact same video.
In this manner you get the maximum perks with minimum disadvantages.
is site very god for email sender
I have direct experience with not receiving emails forwarded from my site's contact from due to others on the shared host spamming.
I am producing an advertising company and am confused on one specific subject - email blacklisting. My confusion is the following:
We are going to be hosting a range of websites. Each website will have the capacity to send e-mail newsletters from their pointed out domain-name. I'm checking out a blacklist service. However, my concern is - because all the hostnames come from my server IP, why would I examine the sites hostname rather of simply my IP? Does this make good sense at all? So, in summation, my concern is - do blacklist services check my IP address, or the hostname that it's being submitted from? How particularly do blacklists work? Likewise, are there any free services offered?
Thanks!
