Considering the security and privacy of the recipient's address, and for technical reasons, there can't be a system that accurately identifies which emails landed in the lead's inbox and which went to their spam folder.
However, our Inbox Placement feature can check if your emails land in the inbox, promotions, or spam folders and gives detailed deliverability insights.
It helps by automating placement tests, providing insights into blacklists, spam triggers, and email health, allowing you to optimize campaigns and improve deliverability while spending less time on manual tasks.
In a nutshell, ultimately deliverability of the email accounts can only be speculated based on the following factors.
Your own domain's reputation and how old it is.
Reputation of email service provider's IP.
Whether or not you are using SPF, DKIM AND DMARC.
If there are any links/images that you have included - even the open tracking pixels can have an impact.
You can also check your deliverability score (and if everything is set up correctly) by going by the following:
Campaign - Sequence editor

Pro Tip for better deliverability:
Be sure to keep your email content relevant and valuable to your recipients.
Optimize your subject lines: Use subject lines that accurately reflect the content of your email and avoid using misleading or clickbait subject lines.
Make it easy to unsubscribe: Provide a clear and easy-to-find unsubscribe link in your emails to help reduce the number of spam complaints, or let the user know they can unsubscribe at any time by replying to you.
Regularly clean your email list: Remove inactive or invalid email addresses from your list to avoid bounces.
Test and optimize your email campaigns: Conduct A/B testing and analyze the results to continually improve the effectiveness of your email campaigns.
Use a reliable email service provider: Choose an email service provider that has a good reputation and provides the necessary tools and features to ensure deliverability.
