Email deliverability (on Apollo.io) - adding tracking domain vs. Mailgun

Hi!

I use Apollo.io for my email campaigns and my bounce rates have increased in December. Did not have that problem before. I use an email warm up provider and have SPF. DKIM and DMARC correctly set up. My email score on mailtester website is 9/10, so blacklisting is not the issue either.

Apollo recommends to set-up a tracking domain through CNAME, as the tracking pixel can be viewed as spam. Alternatively, I could go through Mailgun so that tracking is done there and then integrates automatically with Apollo.io.


Any of you experienced similar spam issues and have any recommendations? One of the actions I just took is to delete my website link from my signature as I heard that can also create deliverability issues.

Thanks for the help!
