Questions & Answers about watashi wa kaigi no mae ni deeta o meeru de okurimasu.

Why does the sentence start with 私 は? Can I drop 私?

私 means “I,” and は marks it as the topic of the sentence: “As for me, …”

In natural Japanese, if it’s clear from context who the subject is, you usually drop 私. So:

• 私 は 会議の前にデータをメールで送ります。
• 会議の前にデータをメールで送ります。

Both can mean “I will send the data by email before the meeting,” if context already makes it clear it’s about you.

You would keep 私 if:

• You’re contrasting people: 私は送りますが、田中さんは送りません。
  “I will send it, but Tanaka won’t.”
• It’s the first time you mention yourself in that conversation and you want to be explicit.

What exactly does the particle は do here? Why not が?

は after 私 marks topic, not grammatical subject in the strict sense. It sets the “frame” of the sentence: “As for me…”

If you said 私が会議の前にデータをメールで送ります, with が, it highlights 私 as the one who performs the action, often with a sense of contrast or focus:

• 私が送ります。 – I will send it (not someone else).

In this neutral sentence where you’re just saying what you (the speaker) do, 私は is the most natural. が would sound like you’re stressing you in particular as the sender.
