If you have set up your sender authentication records they’ll definitely help, but they could not be sufficient. There are some additional actions you can take to increase the credibility of your email sending company and increase your performance with email campaigns:
Each time you send an email, examine your mail server’s IP against DNS blacklists that are based on DNS. You can make use of the MX Lookup tool to see whether your server’s IP is listed as blacklisted. If so, there’s no harm in contacting the administrators of these websites and asking them what they can do to remove you from the blacklist https://www.growbots.com/blog/how-to-test-email-deliverability-and-verify-email-addresses/.
Join email delivery services. These services function as whitelists and assure email is delivered to the person who needs it. After you sign-up your server’s IP is added to their database. The ISPs examine these databases and, if your IP is in the database then your email is sent. Be aware that delivery of emails is not completely free. There is a month-long cost or the price is determined by the number of emails that are sent.
* Whitelist your server’s address with ISPs. Large ISPs have a process you can follow in order to ease the sending of your emails straight to the user’s Inbox instead of an email bulk mailbox. However, the ISP will not allow you to be whitelisted when you use the shared mail server. The host that owns the server could run in trouble when trying to get the server blacklisted if shared accounts are being used. It has been proven that to deliver emails as efficiently as they can email marketers need to utilize a dedicated server, and then follow the steps that I have described previously. The last important thing to do is adhere to the ISP whitelisting process. There’s also a issue with the volume of emails that are sent out at the same time. ISPs are known to limit the number of messages and allow only the maximum number of emails per minute. There is no longer a time where you could constantly blast out thousands of emails. These days, emails must be divided into segments to allow for leakage into the background over time.
* Don’t change the IP address of your mail server without a justification for it. Certain ISPs have a greater sensitivity with new IP addresses, and they limit the number of emails which can be sent via an IP address that has changed.
* Do not alter you “From” email address without a need. Your recipients already have access your From field, and may have included your From the email address in their whitelists. If you send an email from a different address might cause them to believe it’s spam. They may click the “Report the message as spam” button, or simply delete the email message. If you have to modify the From mail address you should consider sending a brief message to your subscribers prior to the change is made. In this way, they will be able to change your information in their whitelists or address books and your subsequent emails are be more likely to appear within the Inbox.
* Don’t send your initial welcoming email using HTML. It’s best to send the welcome message in plain text, and then, once your subscribers have whitelisted your email address, you can mail your regular newsletters in HTML format. Additionally, certain email providers (AOL, Yahoo, Hotmail and Gmail) do not show images within an HTML message until the user has loaded the email.
In closing, bear in mind that today the reputation issue of the sender is more urgent than ever before. It’s simple to trick anti-spam filters with a few techniques, but it’s not an easy task to get your name back. Your reputation as an email sender is a factor in the effectiveness of your emails so make sure you make a great image of you.
