# MailerSend

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

Email API bundling SMS, with separate retention windows for API logs and activity data.

## Who it suits

Teams sending email and SMS from one provider who need a longer activity window than a debugging log — 30 days of activity data against 7 days of API logs is a distinction the rest of this category does not draw.

Consider something else if Both paid tiers include the same 50,000 emails, so paying three times more buys features rather than volume, and the entry price is the highest here.

## iScore

60 / 100 (80% interval 53–68), rank 10 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:
- Capabilities is thin: 0 of 2 criteria are scored, so it sits near the category middle with a wide interval (56–69). Read the interval, not the point.
- Trust and compliance is thin: 0 of 8 criteria are scored, so it sits near the category middle with a wide interval (57–70). 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.
- Documented but not scored, because the page states it as text with no comparable number or a yes/limited/no (a one-time, usage-based or other-vendor price, or a per-site choice): free_allowance, uptime_sla. Read them on the provider page; the score neither rewards nor penalises what it could not compare.
