Postmetry reference sheet
What this ESP allows
Catalog shared by both pages. Each note carries its source, its date, and its confidence level.
On the right, what our emails say about it: matching, contradicted, never observed despite the volume, too few emails to conclude — or out of reach, when the capability can't be read from an email.
Tracking 7 not verified
Click tracking Yes 1 note · 16/08/2026 Too few emails seen on 51 of 51 emails from 2 brands, 3 months
By default, Omnisend tracks email clicks using a shared domain
Caveat Systematic rewriting ("Omnisend automatically modifies that link"), shared domain by default. No click-tracking switch documented, at any level — the only alternative described is the branded domain, which changes the domain, not the tracking. Nothing on transactional emails.

Preferences page Yes 1 note · 16/08/2026
The Preference Center lets subscribers choose which email types they want
Caveat Available on all plans; customisable fields; a link that can be inserted in promotional emails only. Hosted by the vendor — "the page cannot be hosted on your domain", style cannot be customised. Preference/unsubscribe clicks are not counted in the click rate.

Transactional exceptions Yes 1 note · 16/08/2026
Unsubscribe links can be removed from transactional emails, such as order, shipping
Caveat The link can be removed from transactional emails; it is not removed automatically. Whether open/click tracking is maintained on these streams is not documented: to be observed.

DKIM Yes 1 note · 16/08/2026 Too few emails seen on 52 of 52 emails from 2 brands, 3 months
to view the SPF, DKIM, and DMARC records you need to add
Caveat The exact records (and therefore the DKIM selector) are visible only in the account, on the Domain setup page — our recognition of the sending platform will remain an observation from the corpus. A Mailgun history is mentioned (a domain already authenticated via Mailgun = a conflict to resolve through a CNAME): a useful infrastructure clue.

SPF Yes 1 note · 16/08/2026 Too few emails seen on 52 of 52 emails from 2 brands, 3 months
When verifying your sender domain, Omnisend checks your SPF record
Caveat The exact include: is not published on the page (provided in the account). A notable rule: at least one valid record among SPF/DKIM/DMARC is enough to verify the domain for sending — full authentication is therefore not required.

DMARC Yes 1 note · 16/08/2026 Too few emails seen on 52 of 52 emails from 2 brands, 3 months
Ensure a valid DMARC record with at least a "none" policy
Caveat A minimum policy of p=none is required by the Gmail/Yahoo requirements flow; the choice beyond that (quarantine/reject) is left to the brand. Inheritance of the root domain's DMARC by subdomains is documented on the authentication page.

API Yes 1 note · 16/08/2026 Out of reach
UTM tags can only be updated while the campaign is in draft status
Caveat Documented public API (versions v3 to v2026, scopes campaigns.read/write), covering campaigns and contacts. No endpoint seen that controls tracking per contact; tracking settings are exposed at campaign level (UTM). The full contacts reference remains to be reviewed.

Postmetry corpus
Observed in our corpus
Recorded by our analyzers on messages received on addresses we control. Nothing from the reference sheet here, no access to the tool.
52 messages, 2 brands, below the threshold of 30 messages and 8 brands: no rate is published. A percentage on so few emails, or so few brands, describes what one brand configured, not what the sending platform does.
Period observed
08/2026 → 29/10/2026
3 months, 2 distinct brands.
Identification signals
What we recognized the sending platform by, message by message.
- omni1 58 %
- omni2 42 %
Limits of this analysis
It doesn't say what a brand has actually configured. A sending platform that allows turning off the pixel says nothing about which brands have done so — that's what a brand's report answers.
It doesn't rank. No score, no recommendation: capabilities don't carry the same weight depending on the use, and that weight isn't ours to set.
A “not checked” cell is not a “no”. It says nobody has gone to look yet, and nothing else.
The corpus does not establish a capability. A rate of observed pixels says what brands send, not what the tool can do.

Does Omnisend rewrite links for click tracking?
Do your emails go through Omnisend?
The sending platform is read from the headers, not from a claim. The report names it, and says where to fix the findings with that vendor.
