How many cold emails can I send per day from Gmail? Every answer opens with the same two numbers: 500 from a personal account, 2,000 from Google Workspace. Both are right, and both are one row of a table with ten. The Google Workspace page they come from publishes five counters for mail you compose yourself, three of which count recipients in different ways. Which one runs out first depends on the shape of your send rather than the size of your list.
Google updated that page on 18 September 2026, and prints a warning above the table: “Limits per day are applied over a rolling 24-hour period, not a set time of day.” No midnight reset to wait for.
The five counters
- Maximum messages per day: 2,000 per user account, 1,500 for mail merge (previously called multi-send), 500 for trial accounts.
- Recipients per message: 2,000 total, with a maximum of 500 external. Submitting over SMTP as a POP or IMAP user drops that to 100 per message, and the Gmail API to 500.
- Total recipients per day: 10,000, counted every time a message is sent. Google's own example is “5 messages sent to 10 addresses count as 50 total recipients.” Mail merge caps this at 1,500.
- External recipients per day: 3,000, counting every address outside your primary domain, including domain aliases and alternate domains.
- Unique recipients per day: 3,000, of which 2,000 external, and 500 external on a trial account. Each address counts once however many times you write to it that day.
Messages from an alias count against these, so do messages sent by a delegate, and so does Gmail's vacation responder. Cross a limit and sending stops for up to 24 hours. On a personal Gmail account the rule is shorter: more than 500 recipients in one email or more than 500 emails in a day, after which Google says you should be able to send again within 1 to 24 hours.
An ordinary outreach day, counted
Start with one to one sending, one message per person, everyone outside your domain. Messages per day caps you at 2,000. Unique external recipients caps you at 2,000 as well. They land on the same number in the same moment, and the two large counters, 10,000 total recipients and 3,000 external, never come close. For one to one outreach from a paid Workspace account the honest answer is 2,000 people a day.
Now group the same people. One message to twelve contacts in To and Cc spends one message and twelve recipients. That looks like free capacity until you check the counter that binds: unique external recipients is still 2,000, so 166 twelve-person messages reach exactly the same 2,000 people that 2,000 individual messages reach. Grouping buys message headroom and leaves the ceiling on people where it was.
Mail merge is the lower ceiling
Gmail's built in mail merge, renamed from multi-send, arrives with its own pair of numbers: 1,500 messages a day and 1,500 total recipients a day. The feature designed for sending one message to many people lowers your ceiling by 500. Building the merge yourself does not escape it: Apps Script quotas are counted separately, and email recipients per day through MailApp is 1,500 on a Workspace account and 100 on a consumer one.
The trial account sentence worth reading twice
Trial accounts sit at 500 messages a day, and the route out is written precisely. Google says limits increase “when your domain has cumulatively paid at least $100 USD (or equivalent)”, then adds: “It can take up to 75 days after meeting this payment threshold for account sending limits to increase.” The payment is a precondition, and the wait runs after it.
That order gets flattened in the guides ranking for this question. Saleshandy's version reads “After $100 cumulative spend or 75 days (whichever comes first)”, which turns one condition plus a delay into two alternative triggers and tells a reader that waiting alone lifts the cap. It does not. Google's own Apps Script page states the same rule with a different number, “At least 60 days have passed since reaching that payment threshold”, so the two pages disagree on the length of the wait while agreeing on its order. Smartlead's guide, the current top result, cites no Google page at all. Plan a new domain's first two months around 500 a day and neither version can catch you out.
What per recipient tracking costs
This is where our own product changes the arithmetic. Attributing an open to a named person inside a group email needs each recipient to receive a physically different message, because otherwise every open arriving through Gmail's image proxy looks identical. Fast Mail Tracker sends one copy per recipient over SMTP submission, the envelope set to that one person while every copy carries the full To and Cc header, so the group still sees the group. Our engineering notes record the trade off in a line: N copies count N times against the Gmail send quota.
Run that through the counters and it is calmer than it sounds. A twelve person tracked send spends twelve messages instead of one, and the unique recipient counter does not move, so the number of people you can reach is unchanged. It bites once your recipient count passes 2,000 inside 24 hours: the message counter becomes the binding one, and you meet it while the external allowance of 3,000 still has room.
Pick the counter that matches the shape of the send you actually make, and the daily volume question stops being a guess.
When a send does meet a wall, the reply code matters more than the wording. A permanent 5xx rejection is treated as a dead address: that recipient is suppressed and the rest of the group still goes out. A 4xx reply, the class Google's over quota responses fall into, is recorded as failed rather than delivered and left unsuppressed, so a quota rejection never gets filed as a bad mailbox.
Plan against the counter that binds
- Count people rather than messages when everyone is new to you: 2,000 distinct external addresses a day on Workspace, 500 on a personal account.
- Treat grouping recipients as a readability decision. It saves message quota you were not going to spend.
- Check the account before you plan volume. A trial account or a young domain sits at 500 until the paid threshold clears and the wait behind it expires.
- Read the published number as a ceiling. Google's limits page closes by pointing at its email sender guidelines rather than naming a safe daily volume, so the specific figures quoted elsewhere as safe are assertions rather than documentation.
Fast Mail Tracker is in early access while Google's security review runs, so places are limited. If you want opens attributed to the person who actually opened, and a sender that tells a quota rejection apart from a dead mailbox, install it from the button below.
Frequently asked questions
How many cold emails can I send per day from Gmail?
From a paid Google Workspace account the practical ceiling is 2,000 a day, because two counters land there together: maximum messages per day is 2,000, and unique external recipients per day is 2,000. From a personal Gmail account it is 500 emails a day, or 500 recipients in a single email. Trial Workspace accounts are held at 500 messages a day. All of these apply over a rolling 24 hour period rather than resetting at midnight.
Does Gmail mail merge let me send more emails per day?
No, it lowers the ceiling. Google's sending limits table sets mail merge, previously called multi-send, at 1,500 messages per day and 1,500 total recipients per day, against 2,000 messages for ordinary sending. Building your own merge with Apps Script is counted under separate quotas: email recipients per day through MailApp is 1,500 on a Workspace account and 100 on a consumer account.
What counts toward the Gmail daily sending limit?
Messages sent from an alternate address or alias, messages sent by a delegated user, and messages sent by Gmail's vacation responder all count. Google publishes five counters for mail you compose yourself: messages per day, recipients per message, total recipients per day, external recipients per day, and unique recipients per day. Total recipients counts each address every time a message is sent, so five messages to ten addresses count as fifty. Unique recipients counts each address once a day.
Why is my Google Workspace account limited to 500 emails a day?
That is the trial account limit, and time alone does not lift it. Google's sending limits page says limits increase once your domain has cumulatively paid at least 100 US dollars, and that it can take up to 75 days after meeting that payment threshold for the increase to apply. Google's Apps Script quota page states the same order with a different figure, at least 60 days since reaching the threshold. Guides that describe it as 100 dollars or 75 days, whichever comes first, have reversed the relationship.
Does email tracking use up my Gmail sending limit?
Per recipient tracking does, because attributing an open to a named person in a group email requires a separate copy per recipient. Fast Mail Tracker sends one copy per person over SMTP submission while stamping the full To and Cc header on each, so a twelve person send spends twelve messages instead of one. The unique recipient counters are unaffected, so the number of different people you can reach in a day does not change. It becomes the binding limit only once your total recipient count passes 2,000 inside 24 hours.
