Questions & Answers about Setelah saya kirim email, Ibu Dini membalas dengan kabar baik.

Why is it saya kirim email and not saya mengirim email?

Both are correct. Saya kirim email is very common in everyday spoken Indonesian (it drops the meN- prefix), while saya mengirim email is the more formal, fully affixed form. In careful writing, prefer mengirim. Your sentence would be perfectly fine as: Setelah saya mengirim email, Ibu Dini membalas dengan kabar baik.

When should I use mengirim, mengirimkan, and mengirimi?

• mengirim [thing] (kepada/ke [person]): the default, neutral form. Example: Saya mengirim email kepada Bu Dini.
• mengirimkan [thing] (kepada/ke [person]): often interchangeable with mengirim; sometimes adds a slight “for someone” nuance or just sounds a bit more formal. Example: Saya mengirimkan email ke Bu Dini.
• mengirimi [person] [thing]: focuses on the recipient; takes the recipient directly. Example: Saya mengirimi Bu Dini email.

Can I say Setelah mengirim email, Ibu Dini…?

Be careful: Setelah mengirim email, Ibu Dini membalas… normally implies that the one who sent the email was Ibu Dini, because the subject of the setelah-clause is understood to be the same as the main clause’s subject. To keep your original meaning (you sent it), say Setelah saya mengirim email or Setelah saya kirim email.
