How to email many people at once without using BCC

What is the difference between To, Cc and Bcc?#

Bcc does hide the addresses, which is why it is the habit everyone falls into. What it cannot do is the rest of the job.

Why does BCC break on a real list?#

• Everyone is greeted by nobody. One body goes to 300 people, so the first line says "Hi there" or nothing. Personalising it means typing 300 emails.
• A reply can still expose the group. Bcc hides addresses at delivery, but a reply-all on a visible address, or a forwarded copy, puts the thread in front of people who were meant to stay hidden.
• Your provider caps it and does not warn you. Microsoft publishes no fixed number for Outlook.com and says its sending limits vary with your usage history and are lower without a subscription. The cap is real, and it is not a setting you control.
• Spam filters read a large hidden audience as a junk pattern, especially with no unsubscribe link in the message.
• You learn nothing. There is no open or click report and no bounce list, so all you know is that you pressed send.

Is showing customers' addresses to each other a problem?#

When is BCC the right tool?#

For a small, related group who all know each other: a club committee, a class of parents, a team. Do these four things and it stays an honest tool.

1. Put your own address in To, so a reply comes to you instead of scattering.
2. Say so in the first line: sent as a blind copy so nobody's address is shared.
3. Keep the body the same for everyone, and do not greet people by a name you cannot fill in.
4. Send from a domain you control rather than a free address, and keep the group under a hundred people.

If the group does not know each other, or the message is selling something, Bcc is the wrong tool at any size.

What does sending individually mean?#

A sending tool does not put your list into one envelope. It writes a separate message for each person, fills a placeholder from your list, and sends 300 individual messages. That gives you four things at once.

• Each reader sees only their own address, so there is nothing to leak.
• The first line can carry their own name.
• Anyone can unsubscribe themselves without writing to you.
• You get a per-person report of opens, clicks and bounces.

It is also why a real bulk send needs consent on file. Once mail is individually addressed and individually tracked, sending to people who never asked is not a grey area. Any tool worth using makes you prove the address opted in before the list goes out.

If you are doing any of this inside Outlook, the template features and what they cannot do are worth ten minutes first.

How do I start the email itself?#

Whatever the technical route, the first line does the work. Say who you are and why this person is getting it, in one sentence, before any pitch. "We have not written before. You bought a chair from us in March, and this is about the cushion that came loose" beats a logo and a headline every time, and it is the sentence that keeps spam reports down.

How many people can I email at once from Gmail?#

Google prints the number on its own limits page, and it is lower than most people guess. A personal Gmail account is blocked once one message goes to more than 500 recipients, or once you have sent more than 500 messages in a day. The page says sending comes back somewhere between one and 24 hours later. Two ceilings, both 500, mean the same thing in practice: a personal Gmail account cannot mail a 1,000-name customer list on any day, at any speed.

Google's own suggested workaround on that page is to put everybody in a Google Group and mail the group address. That does clear the cap, because one message now has one recipient. It fixes nothing else. It is still a single envelope, so no reader sees their own name, and you still get no report of who received it. A group address is a distribution list, which is the right tool when the members chose to join it and wrong when they did not.

How many can I email from Outlook?#

Microsoft publishes three numbers for Outlook.com accounts, and the third is the one that catches people.

Microsoft adds the sentence that matters: limits vary with your account's usage history and are lower without a subscription. So 5,000 is a ceiling for a warm account, not a promise to a brand-new one. And "non-relationship" is Microsoft's term for people who do not know you, which describes most of a list you did not build yourself.

The per-message ceiling of 500 is what stops a Bcc blast, in Outlook exactly as in Gmail. A list of 1,000 has to be split into at least three messages. Split it, and you have done the mechanical part of bulk sending while keeping none of the useful parts.

So how do I send an email to 1000 recipients?#

First decide whether the 1,000 know each other. That answer picks the tool.

• A club, a class of parents, a conference room: use one group address. It is free, it takes one message, and everybody on the list agreed to be on it when they joined. Everyone can see the member list, and that is acceptable because they are all members.
• A customer list, a lead list, or anybody who handed you a card once: no personal mailbox can send this in one go. Gmail stops the message at 500 and the day at 500 sends, and Outlook caps strangers at 1,000. Splitting the list across three messages gets the mail out and leaves you with no unsubscribe, no personalisation, and no idea which half of the list was delivered.

Can I email a large group with an attachment or photos?#

This is the version of a mass send that fails most often, because an attachment is not one file. Every recipient's mailbox has to store its own copy, so a folder of photos that weighs 10 MB on your laptop asks 10 MB from each of 500 inboxes. Some of those boxes are near full. Those are the ones that refuse you, and a burst of refusals arriving in the same minute is precisely how a mailbox that sends to strangers looks to a filter.

Neither Google nor Microsoft publishes a fixed attachment ceiling on its sending-limits page. If you have read an exact megabyte figure on a blog, that blog guessed. What you can plan around is the shape of the job: put the pictures somewhere you control, then send one link or the images inside the message body, so 500 people download the same file instead of 500 people being handed a copy of your hard drive.

And if the route you are on is a Word mail merge, the question is answered for you. Microsoft's own mail-merge page states it in one line: Word sends an individual message to each address, you cannot CC or BCC anyone, and you cannot add attachments, only links.

A mass mailing should carry links. Attachments belong in a one-to-one message, where you know the size of the box on the other end.

Can I send personalized bulk emails from Word and Outlook?#

Mail merge is the classic answer to this question, and it is a real answer for part of the job. You keep names and addresses in a table, Word fills a placeholder for each row, and the merge hands Outlook one separate message per person. Each reader sees only their own address on their own copy, which is what Bcc cannot give you.

Four things it still does not do:

• No unsubscribe. Each merged message is a one-way letter with no way to leave the list, and the law expects a working opt-out. The checklist for that is short, and merge satisfies none of it.
• No report. You press merge and then you know nothing. Whether 1,000 messages produced 1,000 deliveries is not the same question, and a merge cannot tell you the difference.
• No suppression. An address that refuses today will be merged again next month, and every repeat refusal costs you.
• It runs on your machine, through your mailbox. Your own domain does the sending, your own reputation absorbs the damage, and if Outlook stalls at row 400 the rest of the list never goes.

For 40 personalised invoices, mail merge is the correct tool and I would not use anything else. Past a few hundred strangers, those four gaps are how people end up on a blocklist without ever understanding what happened.

How do I recognise a real bulk sender?#

Plenty of tools promise bulk email, and some of them are a mailbox with a friendlier interface. Five checks tell you which one you are looking at, and every one of them you can run yourself in ten minutes.

1. Send a test to two of your own addresses. If both arrive with the other address visible, it is one envelope and the tool is a mail client.
2. Look for an unsubscribe link a reader can use without writing to you. Not a sentence saying "reply to stop"; a link.
3. Ask what happens to a bounced address. A real tool takes it out of the list on its own and shows you the list it took out.
4. Open a report after a small send. Opens, clicks and bounces per person, not a total.
5. Watch what it does when you import a list. Anything that never asks where the addresses came from is a tool that will be blamed for your spam reports later.

How do I send a mass email without going to spam?#

The seven things below are in the order they matter. The first two decide more than the rest put together.

1. Mail only people who asked for it. Consent is the whole deliverability argument, because a spam report from somebody who never opted in is the one signal a mailbox provider cannot discount.
2. Send from a domain you own, with its signatures set up. A free address mailing hundreds of strangers is the shape of an abuse report, whatever the content says. SPF, DKIM and DMARC in plain English covers the three records and who owns each.
3. Put one visible unsubscribe link near the top, not buried in grey footer type.
4. Name yourself in the first line, in words a person would say out loud.
5. Start small on a new domain and grow the daily count slowly, so a sudden 2,000 is not the first thing your domain has ever sent.
6. Take every bounced address out of the list the day it bounces, and stop mailing people who left a year ago.
7. Keep the message mostly text and one clear link. A wall of images with three words of text is what spam looks like.

For the rest of the reasons a message lands in the junk folder, why your email goes to spam works through them one at a time.

Does my list size change what I need to buy?#

No, and that is the part the pricing pages of big suites get used to hiding. Costs in this category rise with the number of names you store, which is the part that costs almost nothing. Names are cheap to keep; the money goes into the sending infrastructure and the reputation you borrow when your own is new.

So judge a plan by how much mail it lets you send in a month, not by how many contacts it lets you park. Our free plan is 5,000 emails a month, which is a 1,200-name list going out every week, and it carries no charge and no expiry. Every plan holds as many names as you have.
