Frequently asked questions
Are there free AI email assistants?
Yes. Tools such as Shortwave, Inbox Zero, NewMail AI and Hey Help are marked freemium, so you can try them without paying. Free plans often limit the number of drafts or features, so compare them before choosing one for daily work.
Is it safe to connect an AI tool to my email?
Giving any app access to your inbox means it can read your messages. Read the tool's privacy policy, check what permissions it asks for, and avoid connecting accounts that hold very sensitive client or banking information unless you trust the provider.
Can AI write professional emails for clients?
AI can draft clear, polite replies quickly, which helps freelancers and small businesses respond faster. Always read the draft before sending, correct any details it got wrong and make sure the tone suits the person you are writing to.
What is the difference between inbox assistants and email marketing tools?
Inbox assistants like SaneBox or Fyxer help you sort and answer the mail you receive. Email marketing tools like Mailmodo AI help you write and send campaigns to many subscribers. Pick based on whether your problem is reading mail or sending it.
