SendGrid transparently handles DKIM, SPF, ISP rate limits, content inspection, bounces, and spam reports to help users achieve higher deliverability. SendGrid integrates in minutes by just changing three SMTP settings. We even assign our users their own IP addresses. Companies can now track email clicks, opens, unsubscribes, spam reports, and bounces without writing a single line of code. You can also segment your statistics into categories for better insight into different types of emails sent.
