Target your inbox: Avoid spam and clutter
One of the most important aspects that determines the success or failure of an email marketing campaign is the spam rate. Due to the professional ethics of lawyers and many attorneys, few are targeted for sending spam. Still, this alone won’t save your messages from being flagged by mail security robots or even recipients. The road to the spam folder can also be paved with good intentions.
There are three main ways that emails can be marked as spam.
The first is that the email server, whether it's Gmail, Microsoft, or a local provider like Comcast, scans newly received emails and assigns them a spam score. This score is derived from several factors, such as the sender's IP address, the subject line, and the content of the email. If it receives a high enough spam score, it is automatically marked as spam. Many email hosting and provider services either have their own built-in spam detection systems or have licensed spam detection software that runs on top of their email servers.
The second way things are marked as spam is manually by the recipient. This is when zalo database the recipient clicks on the email and manually moves it to the Spam or Junk folder. Over time, their email client (Outlook, Apple Mail, etc.) will start automatically sending emails from that sender to the Spam mailbox.
The third way is a compound result of the first two. It happens when 1) enough emails are sent from an email address or domain and 2) it is either detected automatically by the server or manually flagged by enough recipients. Email servers and providers share spam information with each other to give them an edge in spam detection. This is called email blacklisting. It usually requires quite a bit of effort and a lot of emails. However, if you send a newsletter by email to a large audience, be careful about the email addresses you use.
