| Free tier | up to 100 emails per month on a free plan granted on request by email to support; public plans start under USD 4 per month for 1,000 emails unit requests; metered on request-count; Paid usage is metered: the emails sent and received in a billing period are counted and added to the bill, with plans from USD 10 per month for 10,000 emails.

| Limits |
counts of things, not rates, so no vocabulary kind names them: up to 50 addresses in the To field of one message. Rate limits apply to high volumes over short periods, with no number stated. |
| Binding | request-rate 100 emails per month is the whole free allowance; the request to support comes first, but the monthly count is what makes the free plan a test allowance. |
| Identity | email Registration asks for an email and a password of at least 12 characters, with no card field. The onboarding then asks for an organization, a domain verified by a DKIM record, and a plan; the public plans are paid by card, PayPal or Apple and Google Pay, and the free plan of up to 100 emails a month is granted only on request by email to support. A domain the sender controls is required; SPF and DMARC records are optional, enabled as two more DNS records with a CNAME to mailer.ohmysmtp.com. |
| Egress | not applicable: an outbound sender |
| Per-object cap | 30 MB total email size on the HTTPS API; up to 50 addresses in the To field |
| Retention | 30 days of email history on every plan (30 days) |
| Interface | rest the HTTPS API at https://app.mailpace.com/api/v1/send, and SMTP at smtp.mailpace.com on ports 25, 587 and 2525 with STARTTLS or 465 with TLS, using the domain's API token as username and password; the interface vocabulary has no smtp term |
| Tooling | curl or any HTTP client, the vendor's libraries for Rails, Laravel, Node.js, Python and Go, or any SMTP client |
| Composes with | the free plan is a test allowance at 100 a month; the paid plan at under USD 4 for 1,000 a month is the usable tier. |
| Reliability | sending IP addresses are shared across customers and static IPs are not offered |
| Notes | The vendor's page on how it keeps delivery rates high lists 'No free plan' among its anti-spam measures and says everyone sending is a paying user. |
| Evidence note | documented no message was sent; smtp.mailpace.com answered a 220 banner on ports 587 and 2525. Whether support grants the free plan, and on what terms, is unverified: behind a request to support. |
