In short, no.
Tracking emails with the plugin alone will not cause your emails to get caught up in spam filters.
However, if you're finding that your emails are getting caught and the plugin is helping to realise that it usually means there is an issue with your DNS Configuration. That is, verifying your existing domain so that recipients spam filters recognise it as a legitimate email.
If you're including more and more hyperlinks within your emails, without proper configuration, any recipient with a secure spam filter will capture your email. Our email plugin will have no effect on this.
If you want more information on setting up your DNS records to ensure they're configured properly, view our FAQ on it here.
