What is the difference between System SMTP and Own SMTP?
With System SMTP we send your emails on our servers and you buy credits, where 1 credit sends 1 email. With Own SMTP you connect your own SMTP or Amazon SES, send unlimited email and pay a flat yearly fee based on contacts.
Which providers can I connect on Own SMTP?
Amazon SES, Mailgun, SendGrid, SparkPost, Elastic Email or any standard SMTP server.
Is Own SMTP cheaper for large volumes?
Usually yes. You pay your provider’s rate plus one flat platform fee instead of a per-email markup, so the cost per email drops as you send more.
Is there a free trial?
Yes. You get 14 days free on both System SMTP and Own SMTP, and no credit card is needed.
How can I pay?
By card, UPI or bank transfer. For billing questions, call +91-88005 67676.
Can I resell GO MAILBOX under my own brand?
Yes. Our white-label reseller accounts let agencies run the platform under their own name and domain. Contact sales to get started.
