Both models use the same platform. The difference is who sends the email and how you pay for it.
One credit sends one email. If your plan has 1,00,000 credits, you can send 1,00,000 emails that month on our warmed-up servers.
Connect Amazon SES, Mailgun, SendGrid, SparkPost, Elastic Email or any SMTP. Send unlimited email and pay a yearly fee based on contacts.
For large volumes, Own SMTP usually costs much less, because you pay your provider rate plus one flat fee instead of a per-email markup.

What is the difference between System SMTP and Own SMTP?

One credit sends one email. If your plan includes 1,00,000 credits, you can send 1,00,000 emails in that month.
