A blacklist is a real-time database of IP addresses or domains that have been known to send spam or malicious content. Many Internet Service Providers consult the blacklist databases in order to filter emails sent to the users within their network.
The result of having the sending IP address or domain on a blacklist can vary from being a small nuisance to a complete block of your email campaigns.
With 1,5 billion users around the world, Gmail takes a huge share of the global email market. There is hardly any email marketer who would not have email subscribers using Gmail on the list.
The question of email deliverability to Gmail recipients is becoming more and more urgent for email marketers.
Email infrastructure is the technical part of your email sending program which goes on behind the scenes and helps if set up properly, deliver the messages to the user’s Inbox.
Sending infrastructure refers to the domains and IP addresses of the servers you’re sending emails from, and email authentication refers to the methods you use to prove that an email sent by you is really coming from you.
A properly configured sending infrastructure and authentication greatly increase your ability to deliver the messages to the Inbox.
Businesses and companies don’t always give priority to their email marketing programs focusing on developing new products, setting up goals and planning the strategies. They often start optimizing the email programs when their open rates drop in times. But the success of the business is closely connected with the success of the email program. The more messages go to the user’s Inbox, the more revenue the company gets.

A couple of months ago, I launched a cold email campaign to partner with non-competing but closely related businesses. These were primarily PR and web design agencies.
From my 2 years of experience with cold emailing, I had learned that people like humorous cold emails.
Yahoo!Mail is a free webmail provider from the Yahoo company that saw the world in 1997. Now it’s one of the three largest mailbox providers with 225 million users.
In June 2017, Yahoo was acquired by Verizon Communications, which also bought AOL in 2015. By now, Verizon has not revealed any plans to combine Yahoo!Mail with other email services.
In Part III of our Email Marketer’s Guide, we will talk about Yahoo!Mail’s filtering process, services, and offerings for recipients and senders.
Hotmail was one of the first web based email services launched in 1996. It was rebranded as Outlook.com in 2013 to align with Microsoft’s desktop email application Outlook. At present, Outlook.com is one of the leading global mailbox providers with 400+ million active users.
Deliverability to Outlook.com and Hotmail.com domains concerns a lot of email marketers as Microsoft has the strongest filtering system which often times sends quite legitimate emails to the spam or junk folder.
Email filters used by mailbox providers do a good job – they keep spam out of our Inboxes. But from the other side, “thanks” to spam filters, every fifth legitimate email never reaches the intended recipient.
What’s more is that every mailbox provider uses its own filtering algorithm to distinguish good emails and spam. It makes it even harder for email marketers to deliver their emails to the Inbox.
Here we’ll take the mystery off to make senders understand the filtering rules of the top three mailbox providers – Gmail, Outlook, and Yahoo!Mail – and help them send their legitimate emails to the Inbox.
The Part I of our Email Marketer’s Guide is dedicated to Gmail.
How to avoid spam filters? Many, if not only every single email marketer has ever asked this question. Spam filters seem to be the main obstacle on the way to the recipient’s Inbox.
Probably you’ll be disappointed if we say that it is not possible to avoid spam filters, but you have to accept that fact. Spam filters are a part of the email delivery process. When you send an email, it is filtered: to the Inbox, to a special tab, to a spam folder, or it is blocked completely.
Filters play a massive role in the email deliverability. That’s why our goal at GlockApps is to help our users understand how spam filters work, how mailbox providers use them, and how to get the emails filtered to the Inbox.
Can't send emails to Yahoo! subscribers? It's highly possible that your sending IP address was blacklisted by this provider.
Users of Yahoo!, Google, Hotmail, and other major mailbox providers are often victims of spammers. Mailbox providers are forced to introduce filters and blacklists to protect their users from unsolicited emails.
