What 1and1Mail is

1and1Mail is a Windows program for sending bulk email through SMTP servers. It lets users organize addresses in address books and groups, import contacts, and personalize messages with fields such as recipient names. Its sending controls include per-mailbox daily limits, delays, and resuming interrupted sends. Email tools include an HTML editor, templates, and macro replacement. The free plan is free and allows 50 emails per send, one sender account, and 50 contacts per address book. A separate free plan is free, with a 50-email send limit, one sender mailbox, and four free AI-written messages. The Personal plan is CN¥680 a year; the Business plan is CN¥1,880 a year. The Lifetime plan is CN¥1,880, paid once. Commercial features include skipping unsubscribe groups and collecting bounce and unsubscribe information. Sending remains subject to the email provider’s limits, and exceeding them may result in a mailbox being blocked. The maker says the software is intended for targeted sending, not very large volumes of unsolicited email.
