What are the storage limits on my 1&1 e-mail?


Each mailbox has a quota of 2 GB or 100,000 e-mails. However, no single e-
mail can be larger than 100 MB.

An e-mail is made up of the e-mail text and an encoded version of any binary
attachments. As such an image file in JPEG format is encoded to base64, this
new version of the JPEG takes up more space than the actual JPEG file, due to the
encoding procedures.

Because of the base64 encoding an e-mail may be limited to a size closer to 70MB.

Instant Domain and Exchange packages have a 1 GB mailbox quota by default, however some limits are changed with account upgrades.

Please note: There is a combined mailbox limit of 25 GB per contract.
