There is no email marketer that has never received bounced emails. Sooner or later bounced emails happen even if you have the cleanest list possible.
From one side, bounce emails are a nasty thing because they negatively influence your sender reputation and deliverability.
From the other side, they do a good job by giving you a plenty of information about the quality of your mailing list, recipient engagement, and your email campaign performance.
You just need to understand what bounce emails tell you in order to determine and address the issues.
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.
Bad email practices typically lead to serious deliverability problems like spam placements, blocked and dropped messages which have a direct negative impact on your sender reputation and email performance.
To protect their users from unsolicited emails, mailbox providers often put bad senders to the blacklist and do not deliver their messages to the target recipients. Gmail, Outlook/Hotmail, Yahoo, GoDaddy and some other major mailbox providers maintain their own blacklists to stop spammers.
One of the common reasons the emails do not reach the target Gmail recipients is the blocking of the email sender by Google. If you are not able to deliver emails to your Gmail subscribers either, then this article will surely help you.
What ISP look at engagement?
Recipient engagement is becoming more and more important in your ability to deliver email to an Inbox though there is only one ISP that looks at an email engagement at a high level. It's Google.
There is a couple of others that do it as well – primary Microsoft and Yahoo. As to all other global and regional providers, they don't look at email engagement when making Inbox or spam decisions. There are a few reasons why:
When Verizon acquired AOL in June of 2015, they started gradually moving their email accounts ending in @verizon.net to AOL.
They required Verizon customers wishing to keep their @verizon.net email address to request the migration of their account to AOL.
Verizon customers who do not request migration to AOL will have their email accounts closed by April 28, 2017.
When you hit "Send" in your email system or email service provider, your email is transmitted to the outgoing mail server and then to the mail server at the receiving ISP, which then decides what to do with your email based on the sending IP's reputation, authentication, your sending practices, and recipient engagement.
These factors directly influence whether or not your email will be delivered and where it will land (Inbox, Spam, Promotions).
Since the release of GlockApps we have tested hundreds of emails and looked through hundreds of reports.
From our experience, we learned that one of the common causes of deliverability problems, in particular, spam placements, was the message content (providing that you have a confirmed opt-in email list and send relevant content).
In an email marketing world, your brand domain is like your identity in the real life.
It's the thing that allows the recipients of your marketing and transactional messages to recognize your messages. It's the thing that helps you build trust and relationship with your recipients and customers. And you must keep that trust because your business often depends on it.
In an attempt to protect users from spam, phishing emails, and other malware, Gmail implemented a new security mechanism that identifies potentially harmful messages from unauthenticated senders and warns users about them.
This update will help Gmail's users differentiate messages received from legitimate marketers and malicious senders, prevent phishing attempts and keep spam out, ultimately freeing up Inboxes for good emails.
