GlockApps
1, 1, 5 and 10 users across its plans; white label and PDF export for spam tests from Growth, and white label DMARC digests.
The short answer
Agencies, teams and white label, in one look.
Warmerly's Agency plan is $179 a month for 100 mailboxes, with client workspaces and an API. GlockApps lists users on each plan (1, 1, 5 and 10), white label and PDF export for spam tests from its Growth plan, and white label DMARC digests. Neither is clearly ahead: the tools serve different client work. Last checked 22 October 2026.

02
Client workspaces share a pool
A new workspace created by an Agency owner becomes a client workspace in the Agency plan, with no extra card, sharing its allowances. Each has its own mailboxes, campaigns and inbox.

03
API on Agency only
API keys, the REST API and webhooks need the Agency plan.

04
Three roles in a workspace
A workspace member is an owner, an admin or a member. Members can use projects and read members, admins can also manage members and branding, and only owners manage billing or delete the workspace.

05
A client workspace shares the pool
Client workspaces share the Agency plan's one pool of allowances, with no extra card, so a new client does not mean a new subscription.

06
Each client is separate
Each client workspace has its own mailboxes, campaigns and inbox, and a new workspace skips the setup wizard.

The 100 mailbox ceiling
Agency covers 100 mailboxes, which is 20 clients at 5 mailboxes each. More needs a custom Max plan.

What GlockApps does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Whether white label is on every plan that lists it
- How client projects are separated in the app
- How much of the white label is customisable, such as logo and domain
- Whether read-only roles can be limited to one client project
- Whether client users can log in to see their own reports
Where the sources disagree
We report each version rather than pick one.
- White label appears under the Growth plan on the spam testing page and again in the API description on the home page. We could not tell whether it applies to every plan.
The numbers
Only what we could verify.
| Measure | Warmerly | GlockApps |
|---|---|---|
| Agencies, teams and white label | Agency is $179 for 100 mailboxes, with client workspaces and a REST API. | 1, 1, 5 and 10 users across its plans; white label and PDF export for spam tests from Growth, and white label DMARC digests. |
| Users on the top listed plan | Not stated by plan | 10 on Enterprise |
| Client separation | Client workspaces on Agency | Projects and folders |
| Agency price | $179 a month | $129 a month on Enterprise |
| Roles | Owner, admin and member | Admin, writer and read-only |
| Clients on the top plan at 5 mailboxes each | 20 | Not stated |
| Postmaster users, Enterprise | No connection found | 10 |
In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Match the client work
Warmerly's workspaces keep each client's mailboxes and campaigns apart. GlockApps' white label reports suit agencies reporting on tests and DMARC.
Do not stretch the labels
GlockApps' audience labels are not stated to map one to one to its plans.
Twenty clients, one invoice
An agency with 20 clients on 5 mailboxes each fits the 100 mailboxes in the $179 Agency plan, which is $8.95 per client a month for the mailbox side. GlockApps would price the same agency by tests and messages, which depends on how often it tests each client.
Reports as a deliverable
If you hand clients a monthly PDF, GlockApps' white label digests are the nearer fit. If you hand them a running campaign, Warmerly's client workspaces are.
Seats are different things
GlockApps counts users per plan, 1, 1, 5 and 10. Warmerly's plans publish mailbox counts, and workspace roles are set per person, so check how many people you need to invite.

Questions
Does GlockApps support agencies?
It lists users on each plan, white label reporting and PDF export, and white label DMARC digests (glockapps.com, read 21 October 2026).
Does Warmerly support agencies?
Yes. Agency is $179 for 100 mailboxes, with client workspaces that share the plan's allowances, and an API.
Does GlockApps let clients see reports?
Its pages list white label PDF export and digests, and a read-only role. We did not read whether a client can log in to a project (read 22 October 2026).
How many client workspaces can an Agency plan hold?
Client workspaces share one pool of allowances and the plan covers 100 mailboxes in all, so the limit is the mailbox count, not a workspace count.
