Grammar Check for a Friendly Business Email to Matt

Hi Camilla, the message you wrote is very clear and friendly! Here are a few small improvements to make it perfect:

• Change "a quick line" to "just a quick note" because it's more common in emails.
• Instead of "(see the bank slip attached)", write "(please see the attached bank slip)" for a smoother tone.
• In the sentence "Sorry it took a bit longer than expected!", you can say "Sorry it took a bit longer than expected." with a period to keep it professional yet friendly.
• In the last sentence, add a comma after "Have a great summer ahead" before the smiley to separate the phrases better.

Here's the corrected version:

Hi Matt,

Just a quick note to let you know we've made the payment (please see the attached bank slip). Sorry it took a bit longer than expected.
It's been a pleasure working with you! Have a great summer ahead, :)

Best wishes,
Camilla
