Have you ever thought of a scenario, where an important message has not hit the client’s inbox and you lose out on the million dollar deal? Deadly! isn’t it?
Here, we explore some of the ways your email can be marked as spam and also the ways to prevent from it.
Flagged as Spam by End User Email Client
While marketers are failing on the permission based email front, an email recipient can mark email as spam in multiple ways. The built-in junk filters can simply mark an email as junk & your emails will not reach their inbox. For businesses with Exchange Server 2007 and Outlook on the desktop, a feature called Safe list Aggregation can take a deep dive in to your emails. Safe list aggregates user’s personal safe list at an individual level and update the block list information onto the server itself. Now, the email address flagged spam by one of the users will also automatically get blocked for other users.
Get the email basics right! Ensure to increase a legitimate subscription rate, allow the users for an easy unsubscribe, provide with a top of the mind recall. These gimmicks will help you avoid such a scenario. Over and above this from name, subject lines, sender names, frequency of emailers can aggravate spamming issue.
Submitted as Spam to Email Security Vendor
Anti-spam software vendors will accept spam submissions from customers so to update their databases for latest spam emails. People have limited memory and they often tend to forget about the emails subscribed to. With this, they can mark the legitimate emails as spam too. Avoid such a scenario by feedback, adding easy unsubscribe buttons and by including information on ‘Why they are receiving this email?’ This will lead to an easy recall.
Sending from Dynamic IP Address
With the technology advancement, email servers can be directed to use the block lists with a capability to reject email from ISP customer IP addresses, which are usually dynamically allocated ranges of IP addresses. Here there can be multiple issues (a.) either the IP you have been allocated was previously sending out the spam emails (b.) or the IP is within a dynamic IP range that is on a block list.
The solution to this can be to either acquire static IP addresses from your ISP to run your email server, or to use your ISP as a smart host to relay outbound email from your server to the internet. Most ISPs offer this service to customers. Because the smart host IP address is more trusted and less likely to be on a block list your emails are more likely to be delivered.
Sending from an Open Relay
Similar to the previous point if your server has been misconfigured or compromised by hackers and is known to be an open relay then you will find your emails getting blocked by anyone using one of the major block list providers.
Failing SMTP RFC Requirements
If your server does not meet all of the requirements specified in the SMTP RFC, your emails might still go unseen. One of the major US ISP that outright blocks your IP address if it does not have a correct reverse DNS entry, and getting unblocked means jumping through quite a few hoops.
Failing Anti-spam Server Framework
There are several anti-spam frameworks available to email administrators, and although none have become an official standard they are often used by email admins as one of many factors in assessing emails for spam. Most framework requirements are very simple to implement, and complying with them only improves your chances of successful email delivery so it is worth the time to configure your servers for them.
Spam words, characters and more…
This last one might seem obvious but if you have actually sent some spam in the past then the likelihood of future emails being treated as spam is much greater. Avoid using special characters in the subject line or keywords that aggravate spam behavior in your email like discount, % off etc. Also, refer to the spam laws for the country where your audience resides.
Spamming is sin and a convoluted problem witnessed by both the end users & marketers. Get going with a checklist and implement preventive solutions on your servers and within your business. Doing this, you will be able to make the most out of your email campaigns and communicate to the lord without any hustle. Spam will take you to the hell’s staircase. Do not Spam.
