Hi Matthew, thanks for this great class, but do you mind if I ask you question? Anyway, I'lll proceed, when I attached PDF to send email it seems its sending corrupted file, somehow that the PDF being sent is ending up just about 1kb where it was supposed to be around 40k or something. I hope you can help me on this one. Thanks.

Good one !

Hi,

I don't understand, it doesn't work at all !

I've well uploaded postmark.php, put my api key, comment the attachment line (to simplify), and nothing happens !?...

Does I forgot something ?

Thanks for your precious help,

Ugo

and of course fill in needed information (from-email, ...)

curl is enabled in my php.ini ... is it sufficient ?

In case it complains about missing curl, you can get it by "apt-get install php5-curl". On non-Debian systems you can use the same package name with "yum" or "aptitude".

Use this to send pdf
$result = $postmark->to("send-to-email")
->subject("Test Mail")
->plain_message("This is a plain text message.")
->attachment('sample.pdf', base64_encode(file_get_contents('sample.pdf')), 'application/pdf')
->send();

I'm having the same issues as hgus. It's like $result is never === true. Is there some other setting I'm missing? I'm running php 5.4.4

The API is sound, you need to set up a signature in Postmark the from address that you're using in the API will need to be the same as that signature. That should get it working.

Nice! so far so good. Thanks!

How should I send html email? Please help. Thanks!
