Multiple recipients
Map CC and BCC columns under More options. How To validation and quotas work in the add-on.
You can add carbon-copy recipients per row with dedicated sheet columns.
Recipient column (To)
Select Recipient column in the sidebar.
For the send button count and column validation, MailG treats a cell as valid when it is a single email address. Prefer one primary To address per row.
No comma-separated To list
Putting several addresses separated by commas in the Recipient column is not supported for the add-on’s validation and row count. Use CC / BCC columns (or extra rows) instead.
CC and BCC columns
- Add columns in the sheet (for example
CCandBCC). - Put an email in the cell (Gmail may accept a list in that cell depending on how you format it — keep it simple when possible).
- Open More options and map CC / BCC.
- At send time, those values are passed to Gmail.
Preview
The preview pane shows From, To, Subject, and body only. It does not display CC/BCC lines even when mapped. Confirm with Send me a test email if you need to verify CC/BCC delivery.
Quotas: MailG vs Gmail
These limits are different:
| Counter | What it counts |
|---|---|
| MailG daily quota | Campaign rows processed (one row ≈ one campaign email job) |
| Gmail sending limits | Recipients Google accepts on that send (To + CC + BCC) |
Examples (Gmail recipient count)
| Row content | MailG quota | Gmail recipients |
|---|---|---|
| 1 To only | −1 row | 1 |
| 1 To + 1 CC + 1 BCC | −1 row | 3 |
| 1 To + 2 CC | −1 row | 3 |
You can still hit Gmail’s daily recipient cap while MailG quota remains. Spreading sends with send pacing helps the account look less like a sudden blast, but it does not raise Google’s hard limits.
Tips
- Prefer BCC when recipients should not see each other
- Leave CC/BCC unmapped when unused
- Validate addresses before a large send
- For large lists, check both MailG remaining quota and your Google account type (personal Gmail vs Workspace)
