ForgeBox is your first stop for when you need some new functionality for your application, be that a utility library, an SDK, a framework, or something else. Today we'll take a look at one of the tools for helping manage sending emails — [cbmailservices](https://www.forgebox.io/view/cbmailservices).

cbmailservices

cbmailservices provides a protocol-based service to send emails as well as mail merge functionality to easily customize emails.

But what about good 'ole cfmail? Well, you can still use it! cbmailservices ships with a CFMailProtocol which will delegate back to cfmail for sending your emails.

You might wonder why you would even use this module? Let me give you two reasons:

Mail Merge

Mail merging lets you specify an email template with tokens that can be replaced per email. This lets you tailor your emails to each user, company, or use case you find.

Here's an example of the mail merging capabilitys of cbmailservices:

var mailService = getInstance( "mailService@cbmailservices" );
var mail = mailService.newMail(
    to = "john@example.com",
    subject = "Mail Services Rock",
    bodyTokens = {
        user = "John",
        product = "cbmailservices",
        link = event.buildLink( "view.cbmailservices" )
    },
    body = "
        

Dear @user@,

Thank you for downloading @product@. Have a great day!

@link@

" ); mailService.send( mail );

This will send the following email:

<p>Dear John,</p>
<p>Thank you for downloading cbmailservices.  Have a great day!</p>
<p><a href="https://www.forgebox.io/view/cbmailservices">https://www.forgebox.io/view/cbmailservices</a></p>

Protocols

A cbmailservices protocol defines how to send an email. This can be through good 'ole cfmail, third party mail services like Postmark and SendGrid, or even just locally to your file system or the console output.

Even better, with ColdBox's environment detection, you can set different protocols for each environment. Here's what a sample config/ColdBox.cfc file might look like:

function configure() {
    mailsettings = {
        tokenMarker = "@",
        protocol = {
            class = "cbmailservices.models.protocols.PostmarkProtocol",
            properties = {
                APIKey = getSystemSetting( "POSTMARK_API_KEY" )
            }
        }
    };
}

function development() {
    mailsettings.protocol = {
        class = "cbmailservices.models.protocols.FileProtocol",
        properties = {
            filePath = "logs",
            autoExpand = true
        }
    }
}

This configuration will log emails locally to the file system in development and use Postmark to send emails for real in production. Nice!

You can write your own protocols as well and even publish them on ForgeBox like the SendGrid protocol for your favorite email service.

Wrap Up

So head on over to your local CommandBox terminal and give cbmailservices a go!

Using CommandBox Docker Images to Perform Bytecode Source Conversions

Using CommandBox Docker Images to Perform Bytecode Source Conversions

There are times when code needs to be shipped in a compiled state. It might be for obfuscation or source protection, it might just because it runs faster that way, without the CFML server needing to compile templates at runtime. It's an excellent use case for production Docker images and code deploy pipelines.
