Gmail Sending Limit: Daily Caps & Recipients (2026)
If you hit a “you have reached a limit for sending mail” error, here are the numbers behind it. Free personal Gmail stops you at roughly 500 recipients per day. Google Workspace raises that to 2,000 messages and 10,000 total recipients per day, with a hard cap of 2,000 recipients on any single message. Cross any of these and Gmail blocks new sends for up to 24 hours.
The Limits at a Glance
Free personal Gmail
- 500 recipients per day (and you can’t send to more than 500 recipients in a single email) — per Gmail Help.
- Counted over a rolling 24-hour window, not a calendar day.
Google Workspace
- 2,000 messages per day (1,500 if you use mail merge).
- 10,000 total recipients per day, of which up to 3,000 are unique external recipients.
- 2,000 recipients per message (max 500 of them external).
- Trial accounts: 500 messages per day and 500 external recipients — per Google Workspace Help.
Why a “Recipient” Is the Number That Bites
Gmail counts recipients, not messages. Every name in the To, Cc, and Bcc fields is one recipient — so a single email to 80 people uses 80 of your daily allowance, not one. A small team blasting a 200-person Bcc twice a day on free Gmail will trip the 500/day cap by mid-afternoon.
That’s also why the per-message ceiling matters. On free Gmail you can’t address more than 500 recipients at once, and on Workspace no single message can exceed 2,000 total (500 external). Splitting one giant email into smaller batches doesn’t help if the daily total still blows past your cap.
How to Send More Without Getting Blocked
- Use a Google Group instead of a giant To/Cc list. Sending to one group address counts differently than naming hundreds of individuals, and Google recommends it for large internal sends.
- Spread sends across the rolling window. Because the limit is a rolling 24 hours, pacing batches a few hours apart avoids a hard wall.
- Move bulk mail off Gmail entirely. Newsletters and marketing blasts belong on a dedicated sender (a transactional or marketing email service), not your inbox.
- For automated app sending, use the right channel. SMTP and IMAP cap at 100 recipients per message; the Gmail API allows 500 per message — so high-volume integrations should send via the API.
- Don’t share an outbound link or auto-forward storm. Auto-forwarding rules are capped at 40 filters per account.
Troubleshooting
How long does a Gmail sending lockout last?
Once you trip a limit, Gmail blocks new outgoing mail for 1 to 24 hours, after which sending resumes automatically. Repeatedly exceeding limits can get the account suspended.
Do Bcc recipients count toward the limit?
Yes. To, Cc, and Bcc all count equally. A 100-person Bcc is 100 recipients against your daily total.
Are Workspace SMTP relay limits different from regular sending?
Yes. The SMTP relay and standard SMTP both cap at 100 recipients per transaction; to send to more you start a new SMTP connection. This is separate from the 2,000-recipient in-app message cap.
Why did I hit the limit when I only sent a few emails?
Each email is multiplied by its recipient count. A handful of large distribution-list messages can total hundreds of recipients and trip the cap even though you “only” sent a few times.

| SMTP / IMAP | within plan limits | 100 |
| Gmail API | within plan limits | 500 |
Carly is an AI executive assistant that lives in your existing Gmail inbox and calendar — it triages, drafts, files, and schedules, but it isn’t a mass-mailer and won’t help you blow past these limits. If you’re spending an hour a day buried in one-to-one email instead of sending bulk campaigns, that’s where it earns its keep, starting at $35/month.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
