A promotional landing page offer for 300 standard SMTP mailboxes, positioned as a 30-day trial before continuing at the listed rate. It includes the same core platform features as any Maildoso SMTP mailbox plan: IP rotation across your mailbox pool, self-healing mailboxes (burned mailboxes are automatically paused for 14 days and brought back into rotation instead of staying broken), automatic safe-link replacement so you can include booking links from your first email without hurting deliverability, and inbox placement tests every 3 days with an up-to-date health score per mailbox.

Note: $0.75/mailbox is the same rate already published for any account with 225–924 total SMTP mailboxes on the standard Custom plan — see How much do SMTP mailboxes cost? Volume pricing tiers. The $1.90/mailbox comparison figure on the landing page doesn't correspond to a published pricing tier.

If you signed up through this trial page and have questions about your billing after the 30-day period, contact us with your account email and we'll confirm exactly what applies to your account.
