Questions people ask
How long should a subject line be?+
Around 30 to 50 characters. Phones show about 35 to 40, so put the important words first.
What are spam trigger words?+
Words like “free money”, “act now” or “100% guaranteed” that spam filters and readers distrust. One may be fine; several hurt.
Should I use emojis?+
One can stand out in a busy inbox. More than one looks like an advert.
