How does SURBL impact email deliverability and what are best practices for avoiding listings?

Email marketer from ZeroBounce shares that implementing double opt-in ensures that only legitimate subscribers are added to your list, reducing the chance of including spam traps or invalid addresses that could lead to SURBL listings.

Email marketer from Email Geeks shares that the consensus from the community is that bad list hygiene will consequently lead to other deliverability problems and not necessarily a direct correlation to the SURBL listing itself.
