Check how your email stacks up to industry best practices before sending to your contacts


Want to improve your email deliverability, opens, and click rates? Our Check for Errors tool helps you send better emails by checking for common mistakes and encouraging you to use industry best practices. We review your subject line, preheader, From email and reply-to addresses, and the links in your email template to make sure your message has the best chance of landing in your contacts’ inboxes and of them engaging with it. You can send your email at any point, but it’s a good idea to review these key factors before sending to your contacts!
