The situation when letters ceased to reach your recipients is not the most pleasant and causes a lot of trouble. The most common cause of this is getting IP into the blacklist (IP blacklist or blocklist). In this article you will read tips on how not to get into black lists and make mailing list for clients as safe as possible.

Not a single company is safe from getting into the Spam folder. Open your mailbox and you will probably see letters from well-known companies in the Spam folder. Even if you send news on a subscriber base, your IP address can still be blacklisted. It is impossible to completely eliminate the possibility of getting into spam, but these risks can be significantly minimized.

If your address is blacklisted, the server may begin to return letters with a notification about blocking. But absolutely any user can check the availability of addresses in spam databases, since such lists are publicly available and anyone can see this information on the Internet.

Almost all blacklisted services are automatic. If you do not send spam for 2-3 weeks, then your address is likely to be removed from the lists. Databases are not interested in the endless growth of their lists, so they try to keep them up to date. On the Pangnote platform, you can also check the availability of IP in blacklists.

Take care of the reputation of the IP address

Each IP address has its own “trust” rating. If it is very low, then accordingly and more likely that the newsletter will fall into spam. For different mailings, for example, business, personal, for clients, use different IPs so that there is no situation when you at once lost contact with all addresses. To do this, you can order a dedicated IP address service from your hosting provider.

The temptation to do the mailing from the free mailbox is very high, as the possibility of getting your IP blacklisted after such mailing is especially high. The most reliable way to register your domain is to attach the name of the company or organization. It is also necessary to sign the domain with special keys DKIM and SPF. On the Internet you can find many special instructions on this subject. If you do not understand how to do this, ask for technical support from your hosting provider and they will certainly help you.

Indicate the real name for sending emails

A letter from an ordinary person will receive more responses than from a robot. Recipients should be able to answer your letter and forget once and for all about the phrase “no-reply”. Messages from robots are mainly sent to the spam folder. If you still need to use the stub address, then make sure that it contains a name. By the way, in some countries it is forbidden to send letters without the ability to answer the sender. Indicate the name of the employee of the company or the name of the company in the column of the sender. This reduces the risk of IP addresses being blacklisted.
