Foreign-language emails get ignored
When an email arrives in a language your team does not speak, it sits. Nobody replies. The customer waits or gives up.
Language barriers
You can't help customers you can't understand. Non-English emails sit unanswered or get a confused reply.
Translation tools are slow
Copy the email, paste into Google Translate, read the result, write your reply, translate it back, paste into email. Five steps for one message.
Robotic output
Free translation tools produce stiff, unnatural text. Your customer gets a reply that sounds like it was written by a machine. Because it was.
No language memory
Every email from the same customer requires you to detect the language again. There's no automatic memory of who speaks what.
Your team reads in their language. Customers read in theirs.
Incoming emails are translated instantly. Replies are translated back before sending. Neither side needs to know a second language.
Instant understanding
Every email arrives translated alongside the original. Your team understands every message the moment it lands.
Zero workflow change
Translations happen automatically in your channel. No copy-pasting, no extra tools, no extra steps.
Natural replies
AI writes fluent, contextual translations. Your customer receives a reply that reads like it was written by a native speaker.
Language memory
MailFellow remembers each contact's preferred language. Future emails are translated automatically with no setup.
Translation that works inside your workflow
AI-powered translation that works invisibly inside your existing workflow.
Auto-detect language
MailFellow uses AI to identify the language of every incoming email. The detected language is shown as a tag on the message card in your channel, so your team always knows what they are dealing with.
Translate incoming emails
Non-English emails are automatically translated and displayed alongside the original text. Your team reads and discusses every email in the language they are comfortable with.
Translate replies back
Write your reply in English (or your team's language), and MailFellow translates it back to the customer's language before sending. The customer receives a natural reply in their own language every time.
Contact language memory
MailFellow remembers each contact's preferred language. Future emails from the same sender are translated automatically. Supports Spanish, French, German, Portuguese, Japanese, Korean, Chinese, Arabic, and more.
