grammar - "would always" in the main clause with present simple in conditional

I have two following examples:

I would always say thank you face to face when I get a present from someone because it's more personal.

If it's a family member I would always send a card.

Could anyone, please, explain to me the usage of "would always" in these examples? I understand the meaning of the sentences, but, first, I'm not exactly sure about shades of meaning. Second, I'd like to understand the underlying grammar rule.

As far as I understand the meaning they both the same meaning as regular zero conditional sentences would have:

I always say thank you face to face when I get a present ...

If it's a family member I always send a card.

It seems to me that these examples don't match any mixed conditionals pattern either because hypothetical meaning of "would"

I would say thank you if you did it for me.

like in (unreal present) second conditional doesn't fit in this case.

So my question is what connotation or shade of meaning "would" add in these two sentences? Would those examples still be correct if we left out "always"?

I tried searching web and different grammar books, I know about many different meanings of "would" but none of those seems to match the pattern.
