I frequently send out articles on Covid to friends and family. Generally, I make the attachment by scrolling screenshot of the article from whichever website with SnagIt. I convert the .snag file to a ,jpg and then use Adobe Acrobat online to convert to a scrolling .pdf

Sometimes, when I email these long pdf attachments, I get bounceback emails from recipient's mail servers that my email is suspected spam.

I see many spam testing websites that offer a limited number of free tests each day, but I do not know which are legit and which are themselves an email address harvesting service to sell to spammers.

Can people tell me which free spam testing services are SAFE to use ???

TIA
