Gmail Sending Limits: How Many Emails Can You Send Per Day?

You have 300 personalized emails ready to go out from Gmail. Or you already started, and Gmail stopped you halfway with "You have reached a limit for sending mail." Either way, you need the real numbers.

A personal @gmail.com account can send 500 emails a day. A Google Workspace account can send 2,000. The limits don't reset at midnight, and when you hit one, Gmail blocks new sends for up to a day. The daily count is only one of several limits, though, and it's a ceiling, not a safe target. This guide covers all of them and explains how to stay well clear.

Gmail sending limits at a glance

These numbers come from Google's help page for personal Gmail accounts and its page on sending limits in Google Workspace.

The Workspace page is much more detailed than the personal one. If you're on @gmail.com, plan around the 500-a-day figure and assume the other limits exist even though Google doesn't list them.

How Gmail counts emails toward the limit

Most "I hit the limit way earlier than expected" stories come down to one of these.

Every recipient counts, every time. Google's Workspace page says addresses in the To, Cc, and Bcc fields all count, and that recipients "count each time a message is sent." One email to three people uses three, not one. The personal-account page only says "500 emails per day" and doesn't explain how multi-recipient messages count, so the safe assumption is the same rule.

The window is rolling, not daily. Google's Workspace page says limits apply over "a rolling 24-hour period, not a set time of day." If you send 400 emails at 10 a.m. on Monday, they still count against you until about 10 a.m. on Tuesday. Google doesn't document a reset time for personal accounts, so plan for them the same way.

Replies and follow-ups are sends too. This is the part most guides leave out. If your outreach uses 450 of a 500-email day and 40 people reply, your answers to them come out of the last 50. A busy campaign can leave you unable to answer the replies it produced.

Sending through an app doesn't add capacity. Mail-merge add-ons, CRMs, and tools that use the Gmail API (Maildriply included) send from your account, so those emails count toward the same daily limit as anything you send by hand. Google's Workspace table even has its own row for Gmail API recipients per message.

What happens when you hit a Gmail sending limit

On a personal account, sending fails with "You have reached a limit for sending mail." Workspace users see "You have reached a limit for sending email" or "You reached a Gmail sending limit."

How long it lasts depends on the account type:

• Personal Gmail: Google says you "should be able to send emails again within 1 to 24 hours."
• Google Workspace: users "can't send new messages for up to 24 hours."

Two other blocks look similar but have different causes:

• "Messages you sent couldn't be delivered." Too many emails bounced, usually because the list had invalid addresses. Google says sending usually resumes in about 24 hours. Fix the list before you send again, or you'll end up right back here.
• "The user you are trying to contact is receiving mail at a rate that prevents additional messages from being delivered." This one is about the recipient, not you. You've sent one person too much, and Google's advice is to reach them some other way.

Whichever one you hit, don't keep pressing Send. Retrying won't get you unblocked any sooner. Move the remaining emails to tomorrow and find out why it happened.

Gmail API quotas vs. Gmail sending limits

If you're building on the Gmail API, you're dealing with two separate systems, and it's easy to confuse them.

The Gmail API quota is measured in units per minute. messages.send costs 100 units, and each user gets 6,000 units per minute per project. That's about 60 sends a minute per user, far more than any account's daily limit allows you to keep up. When you go over it, you get a 429 or a rateLimitExceeded / userRateLimitExceeded error. Google recommends retrying with truncated exponential backoff, waiting a little longer after each failure.

The account sending limit (500 or 2,000 a day) applies regardless of how the email was sent. Retrying in a few seconds doesn't help when you've hit it.

Our send queue handles these as two different kinds of failure. A per-minute rate-limit error from Google is retried with backoff, usually within seconds. When an account reaches its daily cap in Maildriply, we don't retry at all that day. The email goes back into the queue and is rescheduled for just after midnight UTC, with a random delay of up to 30 minutes so a backlog doesn't all go out in the same second. If you build your own sender, separate these two cases the same way. Retrying a daily-limit error in a tight loop just piles up failures. We cover the rest of that architecture in Gmail API vs. SMTP for cold email.

The limit is a ceiling, not a target

An account that sends 499 emails a day is within the rules and can still end up in spam folders. Google's email sender guidelines are blunt about it: "Send email at a consistent rate. Avoid sending email in bursts." They also warn that "immediately doubling previously sent volumes suddenly could result in rate limiting or reputation drops."

So a new account that goes from 10 emails a week to 400 on a Monday morning is taking a big risk, even though 400 is under the limit. Here's how to pace sends so the limit never comes up:

1. Ramp up slowly. If the account has never sent in volume, start with a few dozen emails a day and build up over a week or two. Maildriply does this automatically for dashboard campaigns: a newly connected account starts at 20 sends on day one and steps up over its first week.
2. Spread sends across the working day. 150 emails over eight hours is one every three minutes, which looks like a person working through a list. 150 in four minutes looks like a script.
3. Keep 20–30% headroom. On a 500-email account, plan no more than 350–400 outreach emails a day so replies and normal email have room.
4. Send one-to-one, not Cc or Bcc blasts. Each address counts against the limit anyway, and a single message with 80 Bcc recipients is a pattern spam filters notice.
5. Clean your list first. Bounces lead to a block of their own (see above) and hurt your sender reputation. Remove addresses you aren't confident in before you send.

Google's guidelines also ask every sender to keep the spam rate reported in Postmaster Tools below 0.3%, and ideally under 0.1%. Sending fewer emails to people who are more likely to want them protects that number better than anything else. Our email tracking best practices explain how to use open and click data to cut volume instead of justifying more of it.

When you need to send more than Gmail allows

If you keep running into the cap, ask what kind of email you're sending.

• One-to-one outreach (sales, recruiting, partnerships, follow-ups): upgrading from @gmail.com to Workspace raises the cap from 500 to 2,000, and its unique-recipient limit leaves plenty of room for a single person's outreach. Almost nobody writes 2,000 good cold emails a day.
• Newsletters and marketing blasts: Gmail isn't designed for this. Once you send more than 5,000 messages a day to Gmail addresses, Google treats you as a bulk sender, with extra requirements like DMARC and one-click unsubscribe. A dedicated email service provider is the right tool here.

Maildriply is built for the first case: personal email sent from your own Gmail through the API, with paced campaigns, open and click tracking, and the daily cap handled for you. See how it works, or connect your Gmail and send your first tracked email in a few minutes.

FAQ

Does the Gmail sending limit reset at midnight?

No. Google's Workspace documentation says limits apply over a rolling 24-hour period, not a set time of day, and it's safest to assume the same for personal accounts. Emails you sent at 3 p.m. yesterday count against you until about 3 p.m. today.

Do Cc and Bcc recipients count toward Gmail's limit?

Yes. Google's Workspace documentation says addresses in To, Cc, and Bcc all count toward the per-message and daily limits. An email with one To address and four Bcc addresses counts as five recipients.

Can I increase my Gmail sending limit?

There's no setting that raises the limit on a personal @gmail.com account. Moving to a paid Google Workspace account raises it to 2,000 messages a day. Workspace trial accounts are limited to 500 a day.

Do emails sent through the Gmail API count toward the daily limit?

Yes. API sends leave from your account like any other email, so they count toward the same limits. Separately, the API has its own per-minute quota, which limits how fast an app can make requests.

How many emails can I send per hour from Gmail?

Google doesn't publish an hourly limit for Gmail accounts. In practice, spreading sends evenly over the day matters more than any hourly number, because Google's sender guidelines specifically warn against sending in bursts.
