Running multiple email clients

I use Airmail for it’s ability to work with SpamSieve (I had problems using Apple Mail) BUT I greatly prefer Spark for reading and filing emails. Can I have both Spark and Airmail running at the same time, or will Spark possible interfere with Spam Sieve catching spam? I didn’t see this Q in FAQs, Forum or manual, but maybe I missed it. Thanks.

Yes, that’s fine, and in fact we recommend such setups. The only thing to be aware of is that if Spark moves a message out of the inbox (or marks it as read) before Airmail sees it, it won’t be eligible for filtering.

Thanks, Michael.
