Outlook vs GMX vs Mailo: Compare Access, Formats and Prices
Choose an email account package by the connection your application needs, then compare quantity and price. A familiar provider name is not evidence of better inbox placement, universal website acceptance or a higher sending limit.
This comparison describes the store listings. It is not a measured deliverability study or a promise that any package works with every mail client. For the broader catalogue, start with the email-provider comparison.
Compare the included access first
| Provider | Listed access | Check separately |
|---|---|---|
| Outlook | Standard login credentials or optional Full OAuth + recovery fields | Token type, permissions, Graph versus IMAP compatibility, and recovery-mailbox access |
| GMX | IMAP and SMTP listed as activated | Your client’s authentication method, required address suffix and any recovery requirements |
| Mailo | IMAP and SMTP listed as activated | Your app’s importer, the delivered fields and any required recovery or age specification |
Outlook: select the format deliberately
Outlook packages offer Standard and Full formats. Standard contains email and password; Full adds OAuth, client ID and a recovery-mail field. An OAuth-labelled field alone does not establish its token type, permissions or compatibility with a particular client.
Graph and IMAP are different interfaces, while OAuth is an authentication mechanism. Review the API-access buying checklist and connection guide before choosing a larger package for an application.
GMX and Mailo: confirm the client workflow
Both store listings describe activated IMAP/SMTP. That is a useful specification, but a successful browser login and a successful mail-client connection are separate checks. Confirm the fields your app expects and test one mailbox in that workflow before importing a batch.
A particular domain suffix, account age or recovery method should be confirmed if it is not listed. Phone verification at creation does not answer those questions or remove later provider checks. The PVA explainer distinguishes these attributes.
Compare current package totals
The tables use catalogue quantities and base prices, not a guarantee of additional checkout discounts. Microsoft’s optional Full format is separate. Compare the total bill as well as the per-account cost; a larger pack is useful only when you need the extra accounts.

What this comparison does not establish
The store does not publish comparative inbox-placement or engagement measurements. A provider’s country or domain is not a measured performance guarantee. Account packages are not recipient lists, managed Microsoft 365 subscriptions or services designed for high-volume newsletters.
Before ordering
- Match the listed access and credential format to the application you intend to use.
- Confirm any required domain suffix, minimum age or recovery access before paying.
- Choose a quantity, review delivery and replacement terms, and check the final checkout total.
- Verify a delivery privately and keep the order reference if support is needed.
