I got these questions recently:

“I live in Belgium and want to send out A LOT of query letters. Should I send them via email or regular mail?

Also, I have written two screenplays. Do I send both query letters to the same company or is it better to spread them thin throughout the other companies?”

I would be inclined to pitch both scripts at the same time in one query letter. I mention this here:

I’ve found that snail mail gets a better response but it does take more time and cost more money. Since you’re just starting out I would try a few of each (like 100 emails and 100 snail mail query letters) and see what sort of response you get. From there you can better decide which works best for you.

One thing to keep in mind, however, is if these are your first two scripts they may not be up to industry standards. It takes even the most talented writers at least a few tries to start to get close to a “good script” so if you get a very poor response from your query letters don’t worry too much about it, just keep writing new material and continue to improve.

Also, I’ve written a lot of query letters so check out my other posts, too, as you might find them helpful. https://www.sellingyourscreenplay.com/tag/query-letters/
