Email lets you compose and send messages to clients, attach invoices or other files, fill in template variables, and keep a complete log of everything you've sent. Every message is delivered through Ceum's mail provider and recorded in your email log with its delivery status.
What you can do
Open Email to browse your email log of every message you've sent, compose a new message, or open your email templates to view and edit them.
Composing a message
The compose page has:
- Client — required. Picking a client auto-fills the To field with their primary email. When that client has more than one address, To becomes a suggest field listing all of them, so you can switch to the billing inbox in one click.
- To, Cc, Bcc — recipient fields.
- Subject — supports template variables written as
{{name}}. - Body — multi-line, with the same variable substitution.
- Attachments — files or invoices; see below.
As you type, the subject and body are checked: any {{variable}} that isn't part of the current template warns you before you send.
Templates and variables
Five built-in templates supply the wording — one for a plain message to a client, one for sending an invoice, one for chasing an overdue one, and one each for a project and a task. Each carries its own fixed set of {{variable}} placeholders, and each can be reworded on the email templates page. What a template is made of, which variables it accepts, and how one is picked when you send are covered in Email templates and the email log.
Attachments
You can attach:
- A file — any file you upload, such as a PDF, image, Word, or Excel document.
- An existing invoice PDF — reuses the invoice's already-generated PDF.
- A freshly generated invoice PDF — generates a new PDF from an invoice on the spot.
When you attach an invoice, the recipient must match the invoice's client email — the form blocks a mismatch so you don't send an invoice to the wrong person.
The email log
Every message is recorded in the email log with its recipient, subject, date, delivery status, and template, whether it was delivered or not. Email templates and the email log covers what a row holds, what you can filter it by, what expanding it shows, how rows are exported, and how long entries are kept.
Quick send from an item
Choosing Email from a client, invoice, project, or task opens the compose form already filled in for you:
- From a client — the Message-to-client template, with the client's name filled in.
- From an invoice — the Send-invoice or Overdue-reminder template (chosen by the due date), with the invoice number, amount, currency, and due date filled in, and the invoice queued as an attachment.
- From a project — the Project-email template, with the project name filled in.
- From a task — the Task-email template, with the task and project names filled in.
Tips and edge cases
- Every send is logged. A sent message is delivered and recorded in your email log with its delivery status; a failed send shows the error on its log row.
- Template variables are fixed. If you need extra dynamic content, write it directly into the body, or compose without a template.
- Invoice attachments check the client's email. If a client has no email on file, you can't send them an invoice until you add one.
Sending limits
To prevent runaway or accidental bulk sending, each account is capped on how many emails it can send within a rolling time window:
- Your limit — set by your plan: 10 emails on Starter, 50 on Plus, and 100 on Pro. The Free plan's limit is 0, so a Free account cannot send email at all.
- The window — a floating 24 hours (the last 24 hours from right now), not a fixed calendar day.
- Live count — only successfully sent messages count toward the limit.
- When you hit the limit — the compose page shows a banner explaining the limit and the Send button is disabled. As older messages age out of the 24‑hour window, capacity frees up again and you can send once more.
- Per-account overrides — Ceum support can set a limit for a single account, and that limit replaces the plan's.
If a send is rejected for exceeding the limit, you'll see an error explaining how many of your allowance you've used.
Recipient changes
Picking a client fills To with their primary address, and offers their other addresses as suggestions when they have any. To stays a free-text field either way — a one-off recipient is always allowed.
If you change To to an address the client does not have on file, a warning appears so an unintended recipient change doesn't go unnoticed — the message is still sendable, the warning is just a heads-up. Choosing one of the client's own addresses raises no warning.
One case is stricter: when an invoice PDF is attached, the recipient must be one of that invoice client's own addresses — any of them, not only the primary. A send to anyone else is refused.
On mobile
The mobile app covers reading and sending:
- Read the log and compose — browse sent emails, open one for its rendered detail and attachments, and compose a new message with template selection, client recipient autofill (with a picker for a client's other addresses), device-file and invoice-PDF attachments, and the same send-quota banner.
- Templates are read-only — you can apply a template when composing, but creating, editing, and deleting templates is web-only.
