Questions

Do I need to install anything?

No. Open sendeia.com on your phone or computer and sign in with your email. You can add it to your home screen for one-tap access.

What kinds of letters can it read?

Start with clear photos of printed English letters, or enter their text. Check the recognized text, especially names, amounts and dates.

Does Sendeia mail the letter for me?

Prepare and review your reply in Sendeia. When mailing is available for your account, review the exact document, address, service and price before confirming. You can also download a PDF to print and mail yourself.

How do reminders work?

Save and confirm the important date, then choose your reminder settings. Email and browser notifications depend on channel availability and your permissions. Check their status in Settings.

Is this legal advice?

No. Sendeia helps with everyday correspondence. Court, immigration and medical matters require a qualified professional; the app does not handle those actions or promise an outcome.
