I have just managed to include music within the email but even on music which lasts 90 seconds it takes a very long time to send and also to receive is there something that I should do to make it faster.The emails are on HMTL and I cannot find anything esle i should do. Can anyone help me with this please.
No-one will appreciate having to wait an age just to listen to a piece of music, especially if it's just to be fancy and has nothing to do with the message you are sending.
If you really feel the need to include music, upload it to a filesharing site then link to it in the email.
