Efter mötet fick jag en bekräftelse på mejl.

Because Swedish main clauses usually follow the V2 rule: the finite verb comes in the second position.

Here, Efter mötet is placed first, so the verb fick must come next, and the subject jag comes after it:

Efter mötet + fick + jag + en bekräftelse på mejl

If you started with the subject instead, then you would say:

Jag fick en bekräftelse på mejl efter mötet.

Both are fine, but the word order changes because of the V2 rule.

Because Swedish usually marks definiteness on the noun itself.

• ett möte = a meeting
• mötet = the meeting

So Efter mötet means after the meeting.

This is very common in Swedish: instead of using a separate word like the, Swedish often adds a definite ending to the noun.

In Swedish, the definite article is often attached to the end of the noun rather than written as a separate word.

So:

• möte = meeting
• mötet = the meeting

English says the meeting, but Swedish often just uses the ending -et or -en, depending on the noun.

Since möte is an ett word, its definite singular form is mötet.

Fick is the past tense of få.

• få = to get, to receive
• fick = got, received

So here fick jag means I got or I received.

This verb is irregular, so you cannot predict fick from the infinitive just by adding a regular ending. It is simply a form you need to learn:

• att få
• får
• fick
• fått

Because bekräftelse is an en word in Swedish.

So the forms are:

• en bekräftelse = a confirmation
• bekräftelsen = the confirmation

You have to learn the gender of each noun, but nouns ending in -else are very often en words, so en bekräftelse fits a common pattern.

Because the sentence is talking about a confirmation, not the confirmation.

Swedish uses the indefinite form when introducing something as new or not specifically identified beforehand:

• en bekräftelse = a confirmation
• bekräftelsen = the confirmation

So if the idea is simply that you received some confirmation, en bekräftelse is natural. If both speaker and listener already knew exactly which confirmation was meant, then bekräftelsen could be possible in a different context.

På mejl means something like by email or via email.

It describes the medium or channel through which the confirmation was received.

So the idea is not that the confirmation was physically on something. It is an idiomatic Swedish expression for communication method.

You will often see similar expressions such as:

• på mejl = by email
• på sms = by text / via SMS
• på telefon = by phone, on the phone

Because på mejl is being used as a general expression for the method of communication, not to refer to one specific email message.

Compare these ideas:

• på mejl = by email / via email
• i ett mejl = in an email
• i mejlet = in the email

So in your sentence, på mejl means the confirmation arrived through email as a medium. It does not mean inside one specific email message in the same grammatical way.

Yes, but the meaning changes slightly.

• på mejl = by email, via email
  This is very natural and idiomatic.
• via mejl = via email
  Also correct, a little more formal or explicit.
• i ett mejl = in an email
  This focuses on the confirmation being contained in one email message.

So:

• Jag fick en bekräftelse på mejl = I received a confirmation by email.
• Jag fick en bekräftelse i ett mejl = I received a confirmation in an email.

Both can work, but på mejl is the more standard way to talk about the communication channel.

Yes, mejl is a standard Swedish spelling and is very common.

You may also see mail, especially in informal writing or because of English influence, but mejl is the more Swedish-adapted spelling.

So for learners, mejl is a good form to recognize and use.
