An email deliverability checker is a tool that helps email marketers and senders evaluate the deliverability of their emails. This tool allows you to test your emails for potential issues that may impact their ability to reach the inbox of the intended recipient.

There are several reasons why it is important to use an email deliverability checker. Some of the key benefits include:

1. Identifying technical issues: The email deliverability checker can help identify technical issues such as incorrect DNS settings, missing SPF records, or invalid MX records that may prevent your emails from being delivered.
2. Spam filter testing: The tool can also test your emails against common spam filters and identify any content or formatting issues that may trigger spam filters.
3. Reputation monitoring: The email deliverability checker can monitor the reputation of your sending domain and IP address, which can help identify any issues that may be impacting your email deliverability.
4. Improving engagement: By identifying and addressing issues that impact email deliverability, you can improve the engagement of your recipients, increase the open and click-through rates, and ultimately boost your ROI.
5. Compliance check: Some of the email deliverability checkers also help to check whether your email is compliant with the laws and regulations like GDPR, CAN-SPAM Act, etc.

To use an email deliverability checker, you simply need to input the recipient’s email address and send a test email. The tool will then analyze the email and provide a report on any issues that may impact deliverability. Based on the results, you can make changes to your email or your email infrastructure to improve deliverability.
