$email->setFrom(['[email protected]' => 'CakePHP Elastic Email'])
    ->setSender('[email protected]', 'Someone')
    ->setTo('[email protected]')
    ->addTo('[email protected]')
    ->setHeaders(['X-Custom' => 'headervalue'])
    ->setSubject('Email from CakePHP Elastic Email plugin')
    ->send('Message from CakePHP Elastic Email plugin');

That is it.

Advance Use

You can also use few more options to send email via Elastic Email APIs. To do so, get the transport instance and call the appropriate methods before sending the email.

Transactional Email

$email = new Email('elasticemail');
$emailInstance = $email->getTransport();
$emailInstance->isTransactional(true);
$email->send();

Custom Headers

You can pass your own headers. It must be prefixed with "X-". Use the default Email::setHeaders method like,

$email = new Email('elasticemail');
        
$email->setFrom(['[email protected]' => 'CakePHP Elastic Email'])
    ->setSender('[email protected]', 'Someone')
    ->setTo('[email protected]')
    ->addTo('[email protected]')
    ->setHeaders([
        'X-Custom' => 'headervalue',
        'X-MyHeader' => 'myvalue'
    ])
    ->setSubject('Email from CakePHP Elastic Email plugin')
    ->send('Message from CakePHP Elastic Email plugin');

Make sure you have enabled custom header from your Elastic Email settings.

Attachments

Set your attachments using Email::setAttachments method.

$email = new Email('elasticemail');
        
$email->setFrom(['[email protected]' => 'CakePHP Elastic Email'])
    ->setSender('[email protected]', 'Someone')
    ->setTo('[email protected]')
    ->addTo('[email protected]')
    ->setAttachments([
        'cake_icon1.png' => Configure::read('App.imageBaseUrl') . 'cake.icon.png',
        'cake_icon2.png' => ['file' => Configure::read('App.imageBaseUrl') . 'cake.icon.png'],
        WWW_ROOT . 'favicon.ico'
    ])
    ->setSubject('Email from CakePHP Elastic Email plugin')
    ->send('Message from CakePHP Elastic Email plugin');

You need to have some credit in your account to send attachments. Otherwise you will get Not enough credit for campaign. error.

Template

You can use the template created in Elastic Email backend. Get the template id by either using their API or from the URL. Set the template id using setTemplate method.

$email = new Email('elasticemail');
$emailInstance = $email->getTransport();
$emailInstance->setTemplte(123);
$email->send();

Template Variables

Elastic Email provides a nice way to replace the template content using template variables. You can use variables like {firstname}, {lastname} in your template and pass their replacement value.

$mergeVars = [
    'firstname' => 'Foo',
    'lastname' => 'Bar',
    'title' => 'Good Title'
];

$email = new Email('elasticemail');
$emailInstance = $email->getTransport();
$emailInstance->setMergeVariables($mergeVars);

$email->setFrom(['[email protected]' => 'CakePHP Elastic Email'])
    ->setTo('[email protected]')
    ->setEmailFormat('both')
    ->setSubject('{title} - Email from CakePHP Elastic Email plugin')
    ->send('Hello {firstname} {lastname}, <br> This is an email from CakePHP Elastic Email plugin.');

Schedule

You can schedule the email to be sent in future date. You can set upto 1 year in future i.e. 524160 minutes.

$email = new Email('elasticemail');
$emailInstance = $email->getTransport();
$emailInstance->setScheduleTime(60); // after 1 hour from sending time
$email->send();
