במקום הקישור שלחתם קובץ, וזה עזר לי הרבה יותר.

Here במקום means instead of.

Literally, it is ב־ + מקום = in the place of, but in normal Hebrew this often works just like English instead of.

So במקום הקישור means instead of the link.

Because the speaker means a specific link, not just any link.

• קישור = a link
• הקישור = the link

So במקום הקישור means instead of the link / instead of the specific link we were talking about.

If it said במקום קישור, it would sound more general, like instead of a link.

In Modern Hebrew, שלחתם is normally a real plural: you all sent.

Hebrew does not usually use plural forms as a polite singular the way some other languages do. So unlike French vous or German Sie, Hebrew usually does not say the plural form just to be polite to one person.

So here שלחתם most naturally means the speaker is talking to:

• more than one person, or
• a mixed group / group treated with masculine plural

Because את is used before a definite direct object, and קובץ here is indefinite.

• שלחתם קובץ = you sent a file
• שלחתם את הקובץ = you sent the file

So the absence of את tells you that קובץ means a file, not the file.

Hebrew word order is flexible, and putting במקום הקישור first gives it emphasis.

The sentence is highlighting the contrast:

• Instead of the link, you sent a file.

A more neutral order could be:

• שלחתם קובץ במקום הקישור

That is also grammatical, but the original wording puts more focus on the instead of the link part.

זה can point back to:

• the file, or
• the whole previous situation/fact: the fact that they sent a file instead of a link

In Hebrew, זה is often used to mean that in the sense of that thing / that fact / what you just did.

So וזה עזר לי can feel like:

• and that helped me, or
• and it helped me

Often English may translate it more naturally as and that helped me.

Because it agrees with זה, which is grammatically masculine singular.

• זה עזר = that/it helped
• If the subject were feminine, you would expect עזרה

Also, if you understand זה as referring back to the whole previous idea, Hebrew still commonly uses masculine singular זה for that kind of reference.

So וזה עזר לי is the normal form.

Usually וזה is better here.

Hebrew often drops subject pronouns, but in this sentence the speaker wants to clearly point back to the previous clause. Without זה, ועזר לי הרבה יותר would feel less clear, because the listener may pause and think: what helped?

So וזה is doing useful work: it ties the second clause back to what was just mentioned.

הרבה יותר means much more or a lot more.

• יותר = more
• הרבה יותר = much more / far more

So עזר לי הרבה יותר means helped me much more.

Hebrew often leaves the comparison unstated if it is obvious from context. Here the unstated comparison is something like:

• more than the link would have helped
• more than before
• more than the alternative

The main change would be the form of שלחתם.

• To one man:
  במקום הקישור שלחת קובץ, וזה עזר לי הרבה יותר.

• To one woman:
  במקום הקישור שלחת קובץ, וזה עזר לי הרבה יותר.

In ordinary unpointed Hebrew, those two singular forms are written the same: שלחת. The pronunciation is different, but the spelling is usually identical.

• To several women:
  במקום הקישור שלחתן קובץ, וזה עזר לי הרבה יותר.

• To several men or a mixed group:
  במקום הקישור שלחתם קובץ, וזה עזר לי הרבה יותר.

So in the original sentence, שלחתם tells you the speaker is addressing a plural masculine/mixed group.
