I am creating a web app where one of the features must be emailing. I do not want to reinvent the wheel and recreate an entirely new email app since my application is use for far more than just email. Is there something that can be used so that the users of my app can log in to their email from within our app? Like an integration of some kind? Looking for any advice on what the community has tried or used before.
Can you describe your use case in a little more detail? What will the emailing feature look like in your app? Should users be able to send one email from time to time or will they send mass emails like newsletters?
You will probably have to use an external email service provider like Brevo, Mailjet, Mailgun and others.
