Our company has many transactional emails that go out routinely; things like receipts, payment reminders, welcome emails, upgrade confirmations, daily reports, etc.
I'm looking for someone that is excellent at writing the HTML for these types of email. As you know, HTML for emails is very different from web. It's also important for these emails to be mobile friendly.
If it makes any difference, all of the emails will be generated through PHP and sent using Sendgrid.
