Email deliverability involves several factors, such as maintaining a clean email list, avoiding spam-like content, and following email sending best practices. Here are some steps you can take to improve your email deliverability.
Warming up an email domain is essential to build a positive reputation with internet service providers (ISPs) and email recipients. When you start sending emails from a new domain or increase the volume of emails sent from an existing one very quickly, ISPs may perceive it as spam or suspicious activity, which can lead to your emails being blocked or sent to the spam folder.
Warming up an email domain involves gradually increasing the volume of emails sent over a period of time, typically several weeks, while monitoring the email deliverability and engagement metrics closely. This process helps to establish a positive reputation with ISPs by demonstrating that your emails are legitimate
If a recipient is expecting to be contacted and opted in to email communication, it's far less likely that they will flag your email as spam and negatively affect your sender score. A good example is providing a contact form on your website for a demo or contact request. This signals a high intent lead that is far more likely to engage with your content.
It's strongly recommended not to contact individuals that have been purchased from a lead list. The quality of lead will be poor and there is a high likelihood that these emails will bounce. If an email is delivered, the recipient is far more likely to flag the email as spam. All of these factors combined can quickly damage the sending reputation of your email domain.
Your Sender Score is a number between 0-100 that represents the reputation of your IP address. Scores above 97 are strong, scores between 90 and 97 are fair but should be monitored closely, and scores below 90 are problematic. It's important to check your score regularly in order to identify issues.
Blocklists are databases that are used by ISPs and email providers to identify bad actors sending an excessive number of emails identified as spam. If your domain exists on a blocklist, that will negatively affect email deliverability. If your domain/SMTP IP is on one of the blocklists below, contact the blocklist service directly to ask for more information on why your IP was blocklisted and next steps to remove your IP from the list.
