Frequently Asked Questions about Sample Letter of Confirmation

When should I send a confirmation letter?

Send a confirmation letter within 24 hours of reaching any formal agreement. This applies to job offers, meetings, bookings, purchases and rental arrangements. Always send one before either party takes action on the agreement.

Does a confirmation letter need to be signed?

Most modern confirmation emails do not require a handwritten signature. A typed full name and contact details are legally sufficient for most cases. For formal contracts, you may add an electronic signature for extra validity.

How long should a confirmation letter be?

A good confirmation letter is between 3 and 6 short paragraphs. It should only include relevant agreed facts and next steps. Never add extra unrelated information to this type of document.

Can I reply to an existing email thread for confirmation?

Yes, but always update the subject line to clearly state it is a confirmation. This makes the document easy to find later in email archives. Avoid burying confirmation details deep in long email chains.

Is an email confirmation legally valid?

Yes, email confirmations are legally recognised documents in almost all countries. They count as written proof of an agreement. Always save a copy of all confirmation emails you send or receive.

What if the other party does not reply to my confirmation?

Send one polite follow up message after 2 working days. State that you will proceed with the agreed terms unless you hear otherwise. This creates a clear paper trail for the arrangement.

Do I need to send confirmation for informal meetings?

You can send a short 1 line confirmation for casual meetings. Even a quick message prevents forgotten appointments. This is good professional practice even for internal team catch ups.

What details must every confirmation letter include?

Every confirmation letter must include an exact date, clear subject line, all agreed terms, and next action steps. It should also include contact information for follow up questions.
