# SMTP2GO

Canonical: https://inetgeek.com/email/smtp2go/

SMTP relay and email API with volume plans, 30 days of reporting on every tier and the lowest published overage rate in this set.

## Who it suits

Steady sending where the overage rate matters more than the plan fee — $0.85 per thousand on Professional is the lowest published here, and 30 days of reporting comes on every paid tier rather than as an upgrade.

Consider something else if A dedicated IP needs the $75 Professional plan, and the entry tier's 10,000 emails is a quarter of what Resend includes for twice the price.

## iScore

65 / 100 (80% interval 58–72), rank 3 of 11 in email — interval overlaps the next rank, so this is an ordering, not a finding.

inetGeek's own reading, computed from sourced facts against category peers by disclosed rules. Not a provider claim. Intervals are 80%; a provider with few documented facts is pulled toward the category middle rather than scored on what little is known.
Read this score with care:
- Trust and compliance is thin: 1 of 8 criteria are scored, so it sits near the category middle with a wide interval (58–70). Read the interval, not the point.
- Adoption is thin: 0 of 2 criteria are scored, so it sits near the category middle with a wide interval (4–96). Read the interval, not the point.
