Comparison Methodology
Last updated: 2026-07-29
Purpose
ApexMail publishes factual, evidence-based comparisons to help developers and procurement teams evaluate transactional email providers. Claims are based on publicly available documentation and pricing pages at the stated review date.
Disclosure Standards
Every comparison page discloses:
| Field | Description |
|---|---|
| Date verified | When the comparison was last checked against live sources |
| Competitor plan compared | Exact plan name and tier referenced |
| ApexMail plan compared | Exact ApexMail plan used for feature-to-feature mapping |
| Monthly volume assumption | The email volume at which pricing is calculated |
| Billing period | Monthly or annual billing used for price comparison |
| Currency | All prices are shown in EUR. ApexMail prices are published in EUR; when a competitor publishes only USD, the EUR figure is converted at the documented reference rate (1 USD = €0.92, 2026-08-19) and the provider’s published USD price is shown in parentheses |
| Tax treatment | All prices exclude VAT unless stated |
| Feature definitions | How each compared feature is defined |
| Source policy | Only public, official documentation and pricing pages |
| Update frequency | Targeted review every 90 days; critical claims reviewed monthly |
| Correction process | Corrections accepted at security@apexmail.ee; verified within 5 business days |
Evidence Fields per Comparison Row
What actually backs a comparison row today:
| Evidence field | Status |
|---|---|
| Feature name | On every row |
| ApexMail implementation | On every row |
| Competitor implementation | On every row |
| Winner callout | Only where a row is objectively decidable; many rows deliberately declare none |
| Inline source references with URLs | Only on the Amazon SES and Mailgun pages, which carry per-row numbered source links |
| Verification date | One review date per page (per-page pricing_as_of, rendered under the table) |
| Reviewer | ApexMail marketing engineering (named on the SES/Mailgun source footnotes) |
Rows on pages without inline source links (SendGrid, Postmark, Resend) summarize publicly documented provider behavior as of the page’s review date, without per-row citation. Where we cannot verify a competitor figure, the cell says so (“not publicly documented”, “see provider pricing”) rather than asserting a number.
Pricing Comparison Rules
- Pricing comparisons use equivalent monthly volumes on both sides.
- Annual billing is compared only when each provider’s current public catalog expressly supports it; no assumed discount is applied.
- Where competitor pricing varies by volume tier, the tier closest to the stated volume assumption is selected.
- Prices are shown in EUR, converted from the provider’s published list price where a provider publishes only USD (reference rate stated on each page; the provider’s native price is shown in parentheses).
Feature Comparison Rules
- Features are compared based on publicly documented availability at the stated plan tier.
- “Available on higher plans” is noted only when the feature is not available on the compared plan.
- “Available as add-on” includes the add-on price where published.
- Features listed as “planned” or “coming soon” are excluded unless a firm release date is published by the vendor.
- ApexMail features listed as “available” must be generally available in production at the time of verification.
Subjective Assessment Policy
- Subjective labels (“better,” “superior,” “basic,” “limited”) are replaced with measurable statements.
- Where a qualitative assessment is unavoidable, it is explicitly labeled as an ApexMail editorial assessment with the criteria stated.
- Competitor advantages are acknowledged explicitly and without qualification.
Correction and Dispute Process
- Vendors or readers may submit corrections to security@apexmail.ee.
- Corrections are verified against official sources within 5 business days.
- Verified corrections are published with a correction date.
- An errata section noting the correction appears at the bottom of the affected page.
Review Cadence
| Check type | Frequency |
|---|---|
| Pricing accuracy (all competitors) | Every 90 days |
| Feature claims (critical rows) | Every 30 days |
| Feature claims (all rows) | Every 90 days |
| Source URL validity | Every 90 days |
| Full re-verification | Every 180 days or on major vendor release |
Limitations
- Comparisons reflect publicly available information at the verification date. Vendors may change pricing and features without notice.
- Enterprise pricing (custom quotes, volume discounts) is not compared unless publicly listed.
- Comparisons do not constitute legal advice, purchasing recommendations, or contractual offers.
- Performance benchmarks (latency, throughput) are not compared unless independently measured by ApexMail under disclosed test conditions.
