Need to improve your store email delivery? We are excited to announce the launch of a new store optimization addon service which enables easy integration of your Invotide store to third-party email delivery services like Postmark, Mailgun and Sendgrid.
What is SMTP?
Simple Mail Transfer Protocol (SMTP) is a widely supported standard for sending email. Most development frameworks support SMTP without the need for any extra libraries, making SMTP the quickest way to start sending transactional email from your online store.
What is Postmark, Sendgrid and Mailgun?

These cloud SMTP providers offer reliable and scalable email sending services, robust API that ensures blazing email delivery for emails sent to your customers like order confirmation email, password recovery and marketing campaigns emails you can set in your Invotide store admin panel.
Why we recommend Postmark?
Postmark is one of the best SMTP provider you can use for all your business email needs.
Email delivery that you can rely on -Your customers don’t frantically refresh their inbox waiting for your next newsletter but their password reset email is another story. If it doesn’t hit their inbox instantly, they care, and then they email support. The extra support burdens your team and hurts your reputation. Your password resets, license keys, account confirmations, and other transactional emails are critical to your business, and it’s imperative that they arrive in your customers’ inboxes immediately. Email delivery is what really matters, and Postmark don’t just claim great delivery but shares email delivery metrics for transactional email right on their Time to Inbox page. Speed is at the core of what defines Postmark as email delivery service.
