The same questions for any vendor, and the rule behind each: the vendor due diligence checklist.

Legal entity from the vendor's own terms. LEI, registered country and parent company from the Global LEI Index (GLEIF); ownership is left empty where GLEIF names no parent. The CLOUD Act row is arithmetic over those countries, not an assessment of risk.
Mailgun data residency

|---|---|---|---|---|
| EU | Terms not stated | — | documentation.mailgun.com | 2026-10-25 |
EU: The document says that with a single account and billing plan, customers can choose to provision new sending domains in the EU environment. It names no plan requirement and no cost.
The same question for every vendor: where SaaS vendors store EU data.
Mailgun's subprocessor list names AWS, Google and Oracle for hosting or infrastructure. Which SaaS vendors run on which cloud, and the sovereign offerings of each: sovereign clouds.

The count outside the EEA is arithmetic over the country column, not a judgement about lawfulness. A transfer outside the EEA can be perfectly lawful; whether this one is depends on your use, not on the vendor.
Every subprocessor in the registry, and which vendors name it: subprocessors.
Processing terms
From the vendor's data processing agreement · read 2026-10-25 · sinch.com
| Term | What the agreement says |
|---|---|
| Transfer mechanism | EU-U.S. DPF |
| Transfer mechanism | SCC module 2 |
| Transfer mechanism | SCC module 3 |
| Transfer mechanism | UK Addendum |
| Transfer mechanism | other |
| Notice of new subprocessors | 30 days in advance, via the subscription mechanism on Sinch's sub-processor page (only for customers who subscribe) |
| If you object to one | Customer may object in writing on reasonable grounds within 10 business days; Sinch won't appoint until steps are taken to address the objection and a written explanation is given; if not resolved, either party may terminate the Principal Agreement for cause |
| Obligations passed to subprocessors | Written agreements requiring sub-processors to provide at least the level of data protection required of Sinch by the DPA |
| Breach notification | without undue delay |
| Deletion when the service ends | Deletes all personal data processed under the DPA within 90 days after the account is terminated, unless the Customer requests its return; statutory record-retention duties are unaffected |
| Getting your data back | Customer may request, by written notice no later than termination, return and/or certificate of deletion of all copies held by Sinch and sub-processors; copy provided in a readable, further-processable form |
| Requests from data subjects | Provides tools (APIs and interfaces) and assists the Customer with data subject requests; notifies the Customer of requests received directly from data subjects |
| Audit | Information to demonstrate compliance on request; on-site inspection by Customer or mandated third-party auditor only if Sinch has not provided sufficient evidence (ISO 27001 certification or independent third-party audit/attestation report); at Customer's cost, with at least 30 days' notice |
| Audit | information reasonably necessary to demonstrate compliance, on reasonable request |
| Processing on your instructions | only to fulfil its obligations under the Principal Agreement and on Customer's documented instructions (in the DPA, orders, service descriptions, support tickets, other written communications or via the Services); Sinch informs Customer if an instruction appears unlawful and may defer it |
| Confidentiality of staff | Personnel of Sinch and its sub-processors authorised to process the data are subject to confidentiality undertakings or professional or statutory confidentiality obligations, and trained in security and data protection |
| Security measures | Reasonable and appropriate documented security measures, as described in Annex 2 |
Terms as the agreement states them. Where it is silent on a term, there is no row; that is not a statement that the vendor does not offer it.

Does Mailgun have a SOC 2 report?
Mailgun states SOC 2 Type 2 on its own page, but does not say there how to get a report. We read this on 2026-10-25.
- Claimed “Sinch Mailgun is SOC 2 Type II and ISO/IEC 27001 Certified, as well as GDPR compliant.”
Source: mailgun.com, 2026-10-25
Of the 114 vendors in this registry whose own pages mention SOC 2, 57 say the report is available on request, 1 links to the report itself, and 56 state it without saying how to get it. The type is the one the vendor names.
Is Mailgun ISO 27001 certified?
Mailgun states ISO/IEC 27001 on its own page, but does not say there how to get the certificate. We read this on 2026-10-25.
- Claimed “Sinch Mailgun is SOC 2 Type II and ISO/IEC 27001 Certified, as well as GDPR compliant.”
Source: mailgun.com, 2026-10-25
Of the 122 vendors in this registry whose own pages state ISO/IEC 27001, 16 link to the certificate, 43 say it is available on request, and 63 state it without saying how to get it. A certificate names the certification body, the scope and the expiry date: those are the three things to check.
| Scheme | Status | Scope | Source | Observed |
|---|---|---|---|---|
| GDPR | Claimed | — | mailgun.com | 2026-10-25 |
| ISO/IEC 27001 · ISO27001 | Claimed | — | mailgun.com | 2026-10-25 |
| SOC 2 Type II · SOC2T2 | Claimed | — | mailgun.com | 2026-10-25 |
Claimed means the vendor asserts the scheme on its own page and offers nothing further. Available on request means the report or certificate exists but sits behind a request, a login or an NDA. Neither is a certificate we have seen. That is a distinction an auditor makes, so we make it too.

What the authority publishes, not what the vendor claims. An entry covers the offering it names and nothing else: a FedRAMP authorisation for a government edition says nothing about the commercial service. No entry is not a finding about security - most vendors never apply - and an entry filed under a name not listed above would not have been found.
What an entry on the Data Privacy Framework List covers, and which vendors hold one: EU-US Data Privacy Framework.
