email-verify | Email library

Not sure why you need that template in S3 instead of keep it in git but this might be what you're looking for

Note that the arguments to render_to_string are a path to a template, and a context dictionary. Fundamentally the issue is ensuring you are passing a template path to render_to_string every time you call it.

In your first post, the issue is not with the line that you've highlighted (html = render_to_string('email/email_confirm.html', context)), that line is actually totally fine and not the source of your errors. Rather the following line where the first argument to render_to_string is a string of the email body: text = render_to_string(email_body, context). There is no rendering to be done here since email_body is already a string of content. You can delete that line entirely and use email_body instead of text elsewhere in your code.

Alternatively you can create a new template for the text body of the email (maybe email/email_confirm.txt) and render that instead of using string concatenation to create email_body.

In the edits, this sequence is problematic:

Instead of regex, you can consider writing a function like this.

Redirect the email_validation.php to index.php page with the GET parameters. http://sample.com/index.php?success=1 and on the index.php page do like

It does require a validation email, but it can be done without maintaining server-side infrastructure. I actually built a platform to do exactly that at https://clicktoverify.net/.

Essentially you just need to add our (small) javascript library to your page. Then you'll be able to send a verification email via our service and execute a client-side callback once the client verifies by clicking the link in their email.

you need to

Today (and probably never) it is not possible to programmatically verify an email address.

The server its at won't for both security and privacy reasons allow that.

And for a good reason. With such solution, spammers etc. could traverse all the servers and get every email address available.

As a note, there are tools out there that claims being email verification solutons. They generally use DNS validations, including MX record(s) lookup, but they can't with 100% accuracy say if an email address exist or not, they can only get what the email server is setup to give them.

Domain name can be though, and NSLookup is one of the services that can do that.

I found a few good reads at SO (where the first is actually a dupe, though can't close it myself)
