If your email has been suspended due to a poor reputation score, it's important to take steps to improve your sender's reputation. Here are some steps you can take:

Investigate the Reason: Review the suspension notice to understand why your email was rejected. It could be due to content, frequency, or other factors affecting your sender's reputation.

Check Sending Practices: Assess your email sending practices. Ensure you're following best practices, such as using opt-in lists, sending relevant content, and maintaining a clean email list.

Check Blacklists: Use online tools to check if your domain or IP is blacklisted. If so, follow the procedures to request delisting.

Check DNS settings: Ensure your domain's DNS settings (SPF, DKIM, and DMARC) are correctly configured.

Contact Your Email Service Provider: Reach out to your email service provider or IT department to understand if there were technical issues or if they can provide insights into the reputation problem.

Adjust Sending Volume: If you've recently increased your email volume, consider scaling it back and gradually increasing it to maintain a positive reputation.

Monitor Feedback Loops: Many email providers offer feedback loops where you can receive notifications if recipients mark your emails as spam. Monitor and act upon these notifications promptly.

Request Review: Some email providers allow you to request a review or provide additional information to restore your sender reputation. Follow their guidelines if applicable.

Monitor your email bounce rate: A high bounce rate can indicate that your emails are being rejected by recipients, which can negatively impact your sender reputation. Fix any issues causing bounces, such as incorrect email addresses or full mailboxes.

Clean up your email list: Remove invalid or inactive email addresses from your list. Sending emails to these addresses can increase your bounce rate and hurt your reputation.

IP Warming: If you've acquired a new IP address or suspect poor reputation, implement an IP warming strategy. Gradually increase your email sending volume over days or weeks while monitoring delivery rates, open rates, and spam complaints.

Be Patient: Reputation recovery might take time. Continue sending high-quality, relevant emails while monitoring your sender reputation.

@Nihal How many suspended email notifications do you have?

If a lot then most likely a common problem, no quick fix but as @Vinay_Kumar  lists above you need to investigate to get to the root of the cause - stitch in time saves nine.

In addition do you have Communications Limits set up? Maybe you are over communicating with your audience.
Are you using segmentations to personalise and target specific audiences with relevant content this could narrow down your investigation if the errors are coming from specific content, audience or emails.

If you are blasting emails at your whole database every time this will be harder to get to the root cause.

One final question are your audience baed in France? As they have the most ferocious firewalls and oftener need verification from sender the first time you email from your domain to the recipient. Check your inbox (from address) and verify each email that requests this.
