You have years of mail stuck in IncrediMail, and Thunderbird has no way to read it. IncrediMail has no export option of its own, so you need a separate tool to move the messages over. IncrediMail Converter is built for that job.
Quick facts
- Version: 6.9
- Platforms: Windows only (Windows 8, 7, Vista, XP, 2000), 32-bit and 64-bit
- Price: licenses start at $49
- Trial: a free demo exports up to 25 emails and contacts
Key features
Get your IncrediMail mail into Thunderbird through MBOX
The tool converts IncrediMail .imm and .iml files to MBOX, the format you use for Thunderbird. It also exports to PST, EML, MSG, EMLx, MBX, PDF, HTML and RTF, so you can move to Outlook, Windows Live Mail or Mac Mail later.
Keep metadata, formatting and attachments
Messages convert with meta data, formatting, read/unread status and attachments. Header fields such as date and time, to, cc, bcc, subject and from stay intact. To keep attachments, you need the attachment data folder alongside the emails.
Convert in bulk and keep your folder structure
Batch mode handles many files in one run, and your folder structure is preserved. The tool can also locate the input files automatically.
Rescue damaged data and contacts
The vendor says it works on damaged or corrupt IncrediMail data, and it converts contacts as well as emails.
Who it's for
It suits anyone leaving IncrediMail 2.0 or 2.5 for Thunderbird or another mail client. It also suits technicians who migrate several mailboxes and want batch conversion.
