Embedded email

I am looking for someone to design an embedded email for our children's swim school. I will provide the text/wording. Ideally a canva template we could then amend when we need to change the text. I have a brand section on our swim school canva. I can share the codes for the colours, logos and details. It needs to be able to be downloaded as a JPEG in order for me to use it in our email software system.
