Implementing email sending with CfMailGun: Need guidance

Other Questions Mailgun
1

I’m struggling to set up email sending using the CfMailGun component. The docs are a bit sparse, and I could use some help getting it working.

Here’s what I’ve tried so far:

apiKey = 'my-secret-key-123'
mailClient = new MailGunClient(apiKey = apiKey)

mailClient.sendMessage(
  domain = 'mysite.com',
  from = '[email protected]', 
  to = '[email protected]',
  subject = 'Testing CfMailGun',
  text = 'Hello there!',
  html = '<h1>Hello there!</h1>'
)

But I’m getting an error about a missing ‘from’ parameter. Any ideas what I’m doing wrong? Has anyone successfully used this component before?

I’d really appreciate a working example or some tips to get this up and running. Thanks in advance for any help!

I’ve actually used CfMailGun in a few projects, and it can be a bit tricky at first. The error you’re getting about a missing ‘from’ parameter is usually because Mailgun is quite strict about the format of the ‘from’ address.

Try changing your ‘from’ parameter to include a name, like this:

from = 'MySite <[email protected]>'

Also, make sure your domain is properly verified in your Mailgun account. Sometimes, even if the domain is set up, it needs to be fully verified before you can send emails.

Another thing to check is your API key. Make sure you’re using the private API key, not the public one. The private key usually starts with ‘key-’.

If you’re still having issues, you might want to try using Mailgun’s API directly with cfhttp. It gives you more control and can be easier to debug. Here’s a basic example:

<cfhttp url=\"https://api.mailgun.net/v3/your-domain.com/messages\" method=\"post\" username=\"api\" password=\"your-api-key\">
    <cfhttpparam type=\"formfield\" name=\"from\" value=\"MySite <[email protected]>\">
    <cfhttpparam type=\"formfield\" name=\"to\" value=\"[email protected]\">
    <cfhttpparam type=\"formfield\" name=\"subject\" value=\"Test Email\">
    <cfhttpparam type=\"formfield\" name=\"text\" value=\"This is a test email.\">
</cfhttp>

Hope this helps you get things working!

hey ethan, i’ve had some trouble with cfmailgun too. make sure ur using the correct api key (starts with ‘key-’) and that ur domain is verified in mailgun.

also, try formatting the ‘from’ address like this:
from = ‘Your Name [email protected]’

if that doesn’t work, u might wanna try using cfhttp to hit the mailgun api directly. it’s a bit more work but gives u more control.

I’ve encountered similar issues with CfMailGun before. One thing that’s often overlooked is the domain configuration. Make sure your sending domain is properly set up and verified in your Mailgun account. This includes adding the necessary DNS records.

Also, double-check your API key. Ensure you’re using the correct key for your domain. Mailgun provides different keys for different purposes, so verify you’re using the right one for sending emails.

If you’re still facing problems, consider using Mailgun’s REST API directly. It provides more detailed error messages, which can be invaluable for troubleshooting. You can use CFHTTP to make the API calls.

Lastly, don’t forget to handle errors gracefully in your code. Wrap your email sending logic in a try-catch block to capture and log any exceptions. This can provide crucial information for debugging.
