JavaScript-How do I implement multiple actions by clicking on a button?

The specific requirements are this:
Now there are some messages that need to be sent by clicking the button
Using mailto, click the button to pop up the default mail window
Also, update the database to mark the recipient of the message as sent
And then show all the unsent recipients.
What should I do with js,php? A little more details, please.

JS to do the queue. The execution of a single task. PHP provides restful API support.

This logic should be wrong, the use of mailto to send mail, should not be able to get the message sent successfully?

Feel that you should PHP SMTP send mail using servers on the server side.

• The user will fill in the recipient, and send the content successfully, then click Send

• JS Get the data and pass Ajax the data to the PHP server

• The PHP service uses the server to send the message to the SMTP specified user, marks the success in the database, and then JS returns the address of the unsent recipient.

• Ajax After the callback succeeds, the address of the received unsent recipient is displayed with an JS operational DOM structure.
