1.2. Bisa jelaskan tentang skema harga Zimbra (pricing)?

Harga Zimbra tergantung pada ukuran instalasi Anda dan jenis bisnis atau organisasi yang Anda miliki. Secara umum:

  • Semakin banyak user mailboxes (kotak surat) yang Anda beli, semakin sedikit Anda akan membayar per mailbox (Harga Tiering)
  • Ada potongan harga/diskon untuk perusahaan-perusahaan Nirlaba(non-profit), pemerintah, pendidikan
  • Layanan Cloud Zimbra menyediakan penetapan harga yang kondusif untuk penerapan skala besar

Berikut contoh:

  • Sebuah perusahaan yang menginginkan 150 kotak surat dari Edisi Profesional: $ 28 x 150 = $ 4.200 per tahun. 
  • Namun untuk Lembaga pemerintah dengan jumlah users yang sama hanya membayar: $ 14 x 150 = $ 2.100 per tahun. 

1.3. Apakah saya bisa membeli Zimbra jika user saya hanya kurang dari 25 mailbox (kotak surat)?

Ada dua pilihan yang bisa disarankan:

  • Beli Zimbra dengan 25 license, dimana kelebihannya bisa untuk perkembangan ke depan dari jumlah users (planning for growth)
  • Coba Zimbra Cloud yang tidak membatasi jumlah users.
