We write many emails every day. Especially if we need to contact someone very often, we might wish to use courtesies in different ways at the beginning and the end of our emails.

The beginning of emails.

It’s a good way to thank your readers at the beginning of the email. It makes sense especially when you have a request afterwards given that they might feel happy if you thank them.

Thank you for contacting us.

You can use this sentence at the beginning if someone writes to consult the service of your company to express gratitude to their interests and concerns.

Thank you for your prompt reply.

When a client or a colleague replies you very quickly, make sure to thank them. If the reply isn’t prompt, just simply remove the “prompt” off. You can also say, “Thank you for getting back to me.”

Thank you for providing the requested information.

If you were asking someone certain info about certain things and it took them some time to send back to you, then use this sentence to express gratitude to their effort anyways.

Thank you for all your assistance.

If someone offers you a special help, make sure to thank them!
If you want to especially express your gratitude towards them, try to use this one, “I truly appreciate your help in resolving the problem.”

“Thank you for raising your concerns.”

Even if a client or your manager questions your work in their email, you should still thank them. This can show your respect and gratitude towards their serious attitude. At the meantime, you can also use “Thank you for your feedback.” at the end of the email.

When you thank someone at the very beginning of the email, usually it means to thank their past efforts, while at the end of the email it usually means gratitude to their help in the future. To thank in advance can gain more willingness and initiative when they act to help.

Thank you for your kind cooperation. If you need your readers to help you in doing something, you should thank them in advance.

Thank you for your attention to this matter.

Same as above, this sentence include your gratitude to the help that they may offer you in the future.

Thank you for your understanding.

Use this sentence if you involve any content that will have a negative impact on your readers.

Thank you for your consideration.

If you are looking for opportunity or well-being, use this as ending.

Thank you again for everything you’ve done.

This can be used as ending, which is different from above. If you have already thanked the readers at the beginning, you can use this sentence, because you can express gratitude towards them again for their kind help.
