Nodemailer pricing

How Nodemailer charges, what to know before you commit, and what you'd pay at your usage — next to what the alternatives would cost for the same thing.

How it charges

In short

Free open-source Node.js library; you pay only for the SMTP server or email provider it sends through.

What the model leaves out

Free open-source Node.js library; it sends through an SMTP server or provider you choose, and that provider's price (or your own mail server's hosting and deliverability work) is yours.

Before you commit
  • It has no sending service of its own: every email goes through an SMTP server or transport (such as Amazon SES) that you set up and pay for.
