Spam filter: 5 tips for the successful delivery of newsletters

The newsletter shipping is an effective tool for online marketing. However, only if the e-mails also arrive at the recipient. However, many spam filters now also classify welcome messages as spam.


Tip 1: Update the distribution list


The return on investment (ROI) of your campaigns can drop with any unrated email. Rabbit eMarketing has 5 tips for successfully bypassing spam filters so that your newsletters do not end up in the spam or junk mail folder, but reach your subscribers.


Tip 2: Spam Check


The first step towards a successful delivery of the newsletter is the careful and regular updating of the distribution list. E-mail providers evaluate the shipping statistics of the e-mail marketers. A high rate of non-compliant emails (bounce rate) is an indication of a spam distributor. This is why these distributors are gladly blocked and the e-mails end up in the junk mail folder. If necessary, delete all bounces immediately from their distributor. Many e-mail tools now automatically delete them.


Tip 3: Sender Reputation


What are spam filters actually for? Spamfilters (advertising filters) not only control the program code of an e-mail, but also react to abnormalities in the text, such as red letters and too many exclamation marks. In the meantime, however, there are a lot of rules for the spam check, which you do not have to check manually, because a good newsletter system simulates a spam check before sending. In addition, there are free tools like SpamAssassin to support. The filter program sorts unwanted e-mails and controls the code of e-mail templates, for example.


Tip 4: Authenticity


The IP address (address in computer networks) plays an important role when sending the newsletter. Often, e-mails are not delivered successfully because the IP address is already known for spam actions. Especially cheap e-mail shipping providers send via IP addresses their profit play actions. It is therefore recommended to secure your own IP address, or to check which companies are using the IP address. Large e-mail service providers, on the other hand, "warm" their IP addresses systematically, but they deliberately send a few more e-mails daily to make the address known to the provider. The providers analyze again, if the e-mails were opened and clicked. With good values, the deliverability and also the reputation of the address increase.


Protect your sender address and prevent third parties from sending e-mails in your name. Unfortunately, it is now possible to use a different sender address for the dispatch without special effort. However, some authentication methods have been developed to avoid this problem. These include the Sender Policy Framework (SPF), Domainkeys Identified Mail (DKIM), Domain-based Message Authentication, Reporting and Conformance (DMARC), and Sender ID. The use of these methods requires that certain settings be made in collaboration with the e-mail provider.


Whitelisting is compulsory for successful newsletter delivery. The Whitelist (white list) is a positive list that summarizes trustworthy companies or programs. Therefore, make sure that your e-mail shipping service provider is a member of the Certified Senders Alliance (CSA). The American counterpart is called ReturnPath. The CSA has created a central positive list in which providers can be registered for a fee. Membership must be certified and meet specific criteria.
