i was wondering lately how i could send emails with only a front-end language like Javascript through Email as a Service apps like sendgrid or mandrill or so.
Sendgrid and mandrill have Curl APIS, so basically i can just do an AJAX post request to their API to send a mail but the thing is, i will have to put my API secret key in the JS file, this means it will be public... while it's supposed to be secret.
On those two apps, there's nothing in the docs concerning front-end use except having your own server which will use the API, but i'm currently on front-end based project. No server programming, the server only renders the assets that's all.
Do you guys know any method or apps of this kind to acheive this ? Thanks
You can use FormSpree. Just provide the url in form action.
Several suugestions
- dropbox forms via jotbox includes encryption and a paid SSL option
- sendgrid using parse cloud instructions
- third party service, eg 123contactform
- use a not-so-secure php form with extra javascript to mask the email address, see responses on this thread including Dave Jarvis' php code
An alternative is to let each user use his or her own outgoing mail server, by using a mailto: link, which allows you to specify the header information and also a quasi-header named “body”, which puts the content you want into the message body.
If you'd like to keep the key secure you can use something like Aerobatic's HTTP Proxy to specify the key and proxy through the server environment.
