Emails are an integral part of modern business communication. If used strategically, they can play a significant role in the marketing and promotion of a product or service. This is where customer communication solutions like SendGrid come into play.

SendGrid can help businesses send transactional emails and launch successful email marketing campaigns in a bid to build better relationships with their clients.
