Sending Bulk Emails Free: Tools, Real Limits and the Rules

Article summary

TL;DR

You can send bulk emails for free, but never unlimited. A personal Gmail account stops at about 500 recipients a day. Free plans of email services cap you by contacts or sends: 250 contacts at Mailchimp, Klaviyo and MailerLite, 300 emails a day at Brevo. Shopify stores get 10,000 emails a month. Past that, Amazon SES costs $0.10 per 1,000.

A personal Gmail account is blocked for 1 to 24 hours once you send to more than 500 recipients in one email or more than 500 emails in a day.
Gmail mail merge needs a paid Google Workspace plan and is capped at 1,500 recipients a day. It adds an unsubscribe link to each email.
Free plans of email services are capped by list size more than by volume: 250 contacts at Mailchimp, Klaviyo and MailerLite on October 14, 2026.
Once you send close to 5,000 messages a day to personal Gmail accounts, Google treats you as a bulk sender for good: DMARC, aligned domain, one-click unsubscribe, spam rate under 0.3%.
Free tools don't change the law: CAN-SPAM fines reach $53,088 per email in the US, and EU marketing email needs consent or the existing-customer exception.

Sending bulk emails for free is possible, but every free option has a hard limit, and the limit is usually lower than the tool's homepage suggests. Below are the real numbers for each route, read on the official pages on October 14, 2026, and the rules that apply once you email your customer list. If you're a store, the question isn't only "which tool is free", it's "which tool still delivers when the list grows".

Can you send bulk emails for free?

Yes, up to a point. There are three free routes: your own mailbox (Gmail, with or without mail merge), the free plan of an email service, and the email allowance bundled with your store platform. None of them is unlimited.

Verdict

On a free plan, the list size usually caps you before the number of emails does. For a store, the bundled allowance of your platform often goes further than any standalone free plan.

How to send bulk email from Gmail for free

A personal Gmail account is the fastest way to email a few hundred people, and the most fragile. Google's limits are about recipients, not just messages: one email to 600 people already crosses the line.1

Export the list. Only customers who agreed to hear from you, with first name and email in a spreadsheet.
Never use To or Cc for a group. Every customer would see every other customer's address. Bcc hides them, but everyone gets the same email with no personal greeting.
Use a mail merge for separate emails. Google's mail merge sample script for Sheets runs on Apps Script, capped at 100 recipients a day on a consumer account and 1,500 on Workspace.4 Marketplace add-ons still send through your Gmail limits.
Add the opt-out yourself. A plain Gmail email has no unsubscribe link. Write one in, and remove people who ask.
Send in batches. Split the list across days and keep room for your normal mail.

For a personal account, stay well under 500 recipients a day, including your normal mail.

If you hit the limit, Gmail shows "You have reached a limit for sending mail" and you can send again within 1 to 24 hours.1

Gmail mail merge in Google Workspace

Gmail's built-in mail merge replaced the older multi-send mode. It creates one copy per recipient, fills in merge tags such as @firstname, and recipients can't see who else got the message.3

What Google's help page says, October 14, 2026

Mail merge works on Workspace Individual, Business Standard, Business Plus, Enterprise Standard, Enterprise Plus, Education Standard and Education Plus. You can add up to 1,500 recipients per message and send to 1,500 a day. Each email gets an unsubscribe link, and you're notified when someone uses it, but you can't export the list of unsubscribed recipients. To pull contacts from a spreadsheet, they must be in its first tab, as text only.3

Mail merge sends count toward your regular daily total. A Workspace user can send 2,000 messages a day, but free trial accounts are held at 500 messages a day, and Google applies these limits over a rolling 24 hours, not from midnight.2 So it isn't free: it comes with a plan you pay for anyway, and it's a fit for a team that already uses Workspace and has a list under 1,500.

Why a personal Gmail address can't carry a real bulk send

Past a few hundred recipients, the problem isn't only the 500 cap. It's the address. Google's sender rules are written for senders who control their own domain.5

You send more than 500 in a dayThe personal account is blocked for 1 to 24 hoursMove the list to mail merge or an email service
You plug your gmail.com address into an email serviceGoogle says not to impersonate Gmail From headers, and that Gmail uses a DMARC quarantine policy for themSend from an address on your own domain
You approach 5,000 messages a day to Gmail accountsYou're a bulk sender, permanently, across your primary domainSet up SPF, DKIM, DMARC, alignment and one-click unsubscribe first
Customers mark you as spamGoogle wants spam rates below 0.1% and never at 0.3% or higherEmail only people who opted in, and make leaving easy

The 5,000 threshold counts messages to personal Gmail accounts, ending in @gmail.com or @googlemail.com, and all messages from the same primary domain add up. Senders who reach it once are bulk senders for good.6 They must publish DMARC, align the From domain with SPF or DKIM, support one-click unsubscribe in marketing messages and show a visible unsubscribe link.5 Since November 2025, Google says non-compliant messages face temporary and permanent rejections, and it recommends honoring unsubscribes within 48 hours.6

The full setup, record by record, with Yahoo and Outlook's rules too, is in our guide to keeping emails out of spam.

Free tiers of email service providers

An email service (ESP) gives you what Gmail doesn't: a signup form, an unsubscribe link handled for you, bounce removal, stats and an address on your own domain. The free plan is a trial of that, with tight edges.

What a free ESP plan gives you

Unsubscribe and bounce handling built in
Sending from your own domain, with authentication records to add
Templates and open and click reports
Signup forms that record consent

Where it stops

Contact caps: 250 at Mailchimp, Klaviyo and MailerLite
Daily caps: 250 a day at Mailchimp, 300 at Brevo
Provider branding in the footer
Automations, scheduling or support limited or missing

Sources: Mailchimp,7 Klaviyo,8 MailerLite,9 Brevo.10

For an ecommerce brand, two facts matter more than the headline number. First, contacts usually count whether or not you email them: Mailchimp pauses sending once you pass the contact limit, and MailerLite locks campaigns above 250 subscribers.7 9 Importing your whole customer file to a free plan can switch it off. Second, free plans tend to cut the automations a store needs most, like welcome and post-purchase flows; Mailchimp's free plan has no automation flows at all.7 Which flows matter for a store is covered in triggered email campaigns.

If you sell on Shopify, check Shopify Messaging before anything else: 10,000 emails a month are included in Basic, Grow, Advanced and Plus, and abandoned checkout automations don't count toward them.12

How to send 1,000 or 10,000 emails at once for free

A single send to a large list is where most free plans break. Here's what each option allows in one go, on October 14, 2026.

Option	1,000 emails in one send	10,000 emails in one send
Personal Gmail	NoBlocked above 500 recipients	No
Gmail mail merge (Workspace)	YesUnder 1,500 a day, on a paid plan	No
Mailchimp, Klaviyo, MailerLite Free	No250 contacts	No
Brevo Free	No300 a day, so four days	No34 days at 300 a day
Sender Free	YesUp to 2,500 subscribers	No2,500 subscribers
Shopify Messaging	YesFrom the 10,000 a month	YesThe whole monthly allowance
Amazon SES	About $0.10 once out of the sandbox	About $1

Sources: provider pages listed above.1 3 7 10 11 12 13

Two warnings with big sends. If many of those 10,000 addresses are Gmail accounts, one send can put you past Google's 5,000-a-day threshold and make you a permanent bulk sender.6 And a large send to a list nobody has emailed in months produces bounces and spam complaints that hurt every later email: warm the list up with your most recent customers first.

Is there a way to send unlimited emails for free?

No. Every free plan above has a ceiling, and the ceilings exist to keep spam off shared sending servers. The search results promising "unlimited" usually mean one of three things.

What 'unlimited and free' usually hides

Self-hosting. A mail server on your own VPS has no per-email fee, but you take on authentication, IP reputation, bounces and blocklists yourself. Rotating several free accounts. Same list, same content, same complaints, spread over more mailboxes that all get flagged. Cracked bulk mailing software. It's pirated, it can carry malware, and it doesn't lift any provider's limit: your mailbox or sending service still enforces its own.

The cheapest legitimate route at volume is pay-as-you-go sending. Amazon SES charges $0.10 per 1,000 emails.13 New accounts start in a sandbox: verified recipients only, 200 messages per 24 hours, one per second. To leave it, you request production access, declare marketing or transactional mail, and confirm you only email people who asked and handle bounces and complaints; AWS gives a first answer within 96 hours.14 SES sends; it doesn't give you a list manager, templates or unsubscribe pages, so it suits a team with a developer.

The rules that apply even when the tool is free

A free tool doesn't lower the legal bar. The rules depend on where your customers are, not on what you pay.

Each separate email in violation of the CAN-SPAM Act is subject to penalties of up to $53,088.

FTC, CAN-SPAM Act: A Compliance Guide for Business

CAN-SPAM, US
Commercial email, B2B included. No false headers or deceptive subjects, identify the ad, a valid postal address, a clear opt-out honored within 10 business days, and you answer for anyone sending on your behalf.15
ePrivacy, EU, art. 13
Marketing email needs prior consent. Exception: customers' details obtained in a sale, for your own similar products, if they can object easily and free of charge at collection and in every message.16
Google sender rules
SPF or DKIM for every sender to Gmail. From about 5,000 messages a day: DMARC, an aligned From domain and one-click unsubscribe.5

Transactional messages, like an order confirmation or a receipt, are exempt from most CAN-SPAM provisions, but they can't carry false routing information.15 Keep them out of your bulk marketing tool's logic: see payment confirmation emails. In the EU, consent is also personal data processing: see GDPR.

Which free option fits your list size

Start from how many customers you'll email and how often, not from the tool's homepage.

Your list	Free options that fit	Watch for
Under 250 opted-in contacts	Mailchimp, Klaviyo or MailerLite Free; Gmail mail merge if you already pay for Workspace	Contact caps count everyone you import
250 to 1,500	Gmail mail merge on Workspace; Sender Free; Brevo Free if you can spread a send over several days	Brevo's 300 a day turns one campaign into a week
1,500 to 2,500	Sender Free; Shopify Messaging on a Shopify store	Branding in the footer; 15,000 or 10,000 a month in total
2,500 to 10,000 sends a month	Shopify Messaging on a Shopify store; otherwise a paid plan or Amazon SES	Over 5,000 a day to Gmail, you're a bulk sender
Above that	NoFree option; Amazon SES or a paid ESP plan	DMARC, alignment and one-click unsubscribe are mandatory at Gmail

Set up a free bulk send to your customer list

Whatever the tool, the order of work is the same for a store.

Pick who can receive marketing. Export only customers who subscribed, or, in the EU, recent buyers covered by the existing-customer exception who were offered an opt-out.
Send from your own domain. An address like news@yourbrand.com, never a gmail.com address through an email service.
Authenticate the domain. SPF and DKIM at least, DMARC before volume grows. The records are explained in our spam guide.
Write the email with the legal basics. Your postal address, a working unsubscribe link, a subject line that matches the content.
Test it. Send to two or three inboxes you control and check merge fields, links and the unsubscribe.
Send to your most engaged customers first. Recent buyers and recent openers, then the rest in batches within your plan's daily limit.
Process unsubscribes and bounces the same day. Google recommends 48 hours at most for unsubscribes; CAN-SPAM's hard limit is 10 business days.

The first batch is a test of your list, not only of your template.

Where the list comes from matters as much as how you send it. A consent checkbox at checkout, unticked by default, is the cleanest source: see guest checkout for where to place it, and how to reduce cart abandonment for the reminders you may send without it.

Where Tagada fits

Tagada doesn't replace your email tool. It runs the part of the store where your customer list and your payment events are created.

How Tagada helps

The checkout behind your customer list

Tagada runs the checkout, with one-click upsells, order bumps, A/B tests, Apple Pay and Google Pay, and subscriptions with trials, billing cycles and automatic payment retries, standalone or alongside Shopify and WooCommerce. Payments route across Stripe, Adyen and Tagada's own processor, TagadaPay, with one set of rules and a cascade on decline. Server-side tracking sends conversions to Meta, Google and TikTok. Pricing is on the pricing page.

Free sending works while the list is small and clean. Once you're past a few thousand customers, pay for sending and spend the effort on what free plans skip: authentication, consent records and unsubscribes handled the same day.

Frequently asked questions

How can I send bulk emails for free?

Pick the route that matches your list. Under 500 recipients a day, Gmail works, ideally with a mail merge so each customer gets a separate email. For a few hundred subscribers, the free plans of Mailchimp, Klaviyo or MailerLite cover 250 contacts. Shopify stores get 10,000 emails a month in Shopify Messaging. Above that, nothing is free; Amazon SES costs $0.10 per 1,000.

How many emails can I send per day with Gmail for free?

About 500. Google's help says a personal account hits a limit when you send one email to more than 500 recipients or more than 500 emails in a day, and sending is blocked for 1 to 24 hours. A Google Workspace account allows 2,000 messages a day, but Workspace is a paid plan, and mail merge stays capped at 1,500.

Can I send 1,000 emails at once for free?

Not from a personal Gmail account, which stops at 500, and not on free plans capped at 250 contacts. Sender's free plan covers 2,500 subscribers, and a Shopify store can send 1,000 emails from its 10,000 monthly allowance in Shopify Messaging. Brevo's free plan would take four days at 300 a day.

Is there a way to send unlimited emails for free?

No. Every free plan has a cap, and mailbox providers and email services limit volume to keep spam off their servers. Self-hosting a mail server removes per-email fees but not the work: authentication, IP reputation, bounce handling. Cracked bulk mailing software doesn't help either: it can carry malware, and your mailbox or sending service still enforces its limits. The cheapest paid route is Amazon SES at $0.10 per 1,000 emails.

What is Gmail's 5,000 email rule?

Google treats anyone who sends close to 5,000 messages or more to personal Gmail accounts in 24 hours as a bulk sender, permanently, counting all mail from the same primary domain. Bulk senders need SPF, DKIM and DMARC, a From domain aligned with SPF or DKIM, one-click unsubscribe, and a spam rate kept below 0.3%.

Is it legal to send bulk emails to my customers?

Yes, within the rules. In the US, CAN-SPAM requires a truthful sender and subject, your postal address, a working opt-out honored within 10 business days, and fines reach $53,088 per email. In the EU, marketing email needs prior consent, except for your own customers, about similar products, if they could opt out at collection and in every email.
