Emailmetry charges USD $36 per annual licence in a shared pool and $5 per monthly extra domain, excluding tax. The ongoing job is to reduce supported SPF lookups and keep sending addresses current.
What Emailmetry charges
Emailmetry is an automatic SPF flattening service. An annual licence costs USD $36 upfront for 12 months and adds capacity for one managed base domain to a shared pool. Eligible subdomains are included. Managed domains above that pool are monthly extras at USD $5 each, billed after the billing month using its peak uncovered count. Prices exclude tax and there is no per-email charge. Your email and DNS provider subscriptions are separate.
| Managed base domains | If all are monthly extras, per billing month | If all have annual cover, upfront for 12 months |
|---|---|---|
| One | USD $5 | USD $36 |
| Five | USD $25 | USD $180 |
These examples use the stated rate with no volume discount. Annual cover and monthly extras can be combined. Monthly extras use the peak uncovered count in your billing month, so your actual bill can differ from these simple examples. The pricing calculator and billing terms explain the options.
Why the service has a recurring charge
SPF lets a receiving server follow up to ten DNS-querying terms during a check, including nested provider references. Flattening replaces supported references with their sending IP ranges, reducing that count. The worked lookup example shows the difference for individual senders.
An ordinary provider include already follows that provider's current record. A flattened list is a copy of the addresses behind it. When the provider adds a sending range, that copy needs updating; when it removes a range, the copy needs to stop authorising it.
The ongoing job is to follow those changes and publish a checked list. Before publishing an update, the service needs to check that it still authorises the intended senders. Keeping an earlier checked version available helps when an update cannot be verified, though that version cannot include later provider changes.
When flattening earns its place
A domain using one straightforward email service may have plenty of lookup capacity. Another may use several services whose nested references take a check past the limit. The second domain has a specific problem flattening can address.
Use the SPF checker to inspect the published record and its references. A lookup warning is a reason to investigate the affected senders, not evidence that every message fails. Invalid syntax or a missing provider record needs separate attention; the supported-policy details explain the service's limits.
The subscription pays for reducing supported lookup chains and keeping the resulting addresses current. It does not remove the need to tell the service when you add or stop using an email provider.
