No matter what your app is about, at one you point you will have to send emails in Symfony2. Even though this process might seem straightforward and easy to apply, it can actually get pretty tricky. Here’s how you can send emails in Symfony2 by properly splitting your functionality and templates.<\/p>\n
<\/p>\n
First off, you’re going to need to add some email data into your As you can see, we’ve also added three parameters that will help us to send emails in Symfony2: contact email, from email and from name.<\/p>\n <\/p>\n Having a MailManager is helpful because the code needed to send emails will only reside\u00a0in a single place. Thus, it will be way easier to maintain. Here’s how\u00a0you should build the MailManager class:<\/p>\nparameters.yml<\/code> file that will tell Swift Mailer<\/a> <\/span>which SMTP server to use. At this point, it would be advised to create an account at an email sending service. For this short tutorial, we’re going to use SendGrid<\/a>.<\/span><\/p>\nmailer_transport: smtp\r\nmailer_host: smtp.sendgrid.net\r\nmailer_user: your_sendgrid_username\r\nmailer_password: 'your_sendgrid_password'\r\nmailer_port: 587\r\n\r\ncontact_email: contact@yourapp.com\r\nfrom_email: hello@yourapp.com\r\nfrom_name: YourApp<\/pre>\n
2. Send emails in Symfony2 using a\u00a0MailManager<\/h3>\n
