Be sure your emails hit the inbox with Flowmailer's SMTP relay service
Relay is defined in the English dictionary as "to receive and pass on. That is exactly what an SMTP relay server does. It receives the e-mail to be delivered and then does exactly that. SMTP relay, by definition, is "just" the name for the process of SMTP, but when you talk about specifically SMTP relaying (or relay server), it often refers to the e-mail service provider you're engaging.
Almost every source system you use has a default SMTP server set up. However, e-mail delivery is often not the main task of those source systems, so there is a lot to be gained by engaging a third party. That third party, the email service provider (such as Flowmailer) does the following for you, among other things:
Delivery of your emails is very important. From your order confirmations, password-forgetting emails, invoice emails, you can't afford for them to get lost or arrive late. One in ten newsletters that don't arrive will survive. But what if 10% of all your invoices don't end up in the inbox? With SMTP relay, you make sure every email arrives quickly and securely in your recipient's inbox.
Flowmailer SMTP servers ensure reliable email delivery by focusing on mail server optimization, supporting and mandating domain authorization (SPF, DKIM and DMARC) where necessary, and maintaining reputation (at the domain and email level).
