Group DM vs Mass DM on Twitter/X: Which One Should You Use?
A group DM puts everyone into one conversation where they can all see each other. A mass DM sends each person their own private message. How the two differ on X, the limits on each, and how to choose the right one for what you are trying to do.
Tweeksocial Team
A group DM on X is one conversation shared by everyone in it. They all see every message and every reply, including each other's. A mass DM is the same message sent to each person separately, so every conversation stays private between you and them. X raised the maximum size of a group chat to 256 people in 2023. A mass DM has no group size at all, only X's daily limit of 500 messages per account.
The short rule: use a group DM when the people in it should talk to each other. Use a mass DM when you want to reach a lot of people and hear back from each of them privately.
The difference at a glance
| Group DM | Mass DM | |
|---|---|---|
| Who sees the replies | Everyone in the group | Only you |
| How many people | Up to 256 in one group | No group size; X allows 500 messages a day per account |
| Personal touch | One message for everyone | Each message can use the person's name |
| How it feels to receive | A conversation you were added to | A message written to you |
| Can people see who else was included? | Yes, everyone can | No, nobody can |
| Leaving | Anyone can leave the group | Nothing to leave |
| Suits | Teams, cohorts, communities, events | Announcements, launches, invitations, check-ins |
When a group DM is the right choice
Group DMs are for groups that already exist, or ought to.
A team or a project. Four people coordinating a launch belong in one conversation. Everyone reads the same thread and nobody has to forward anything.
A cohort or a community. A course cohort, a mastermind group or a small paid community gains from members seeing each other. Introductions, questions and help from other members are the whole point.
An event. Speakers at a conference, the people coming to a meetup, or guests on a podcast series often want one shared place to swap details and times.
In every case, the value comes from people talking to each other, not just to you.
When a mass DM is the right choice
Mass DMs are for reaching many people, one at a time.
Announcements to your followers. A launch, a new course, a change of price, a free resource. Each person hears the news privately and can reply privately.
Invitations. Webinar invitations, early access and first-look offers work better one to one, where saying no is easy and nobody can see who else was asked.
Personal check-ins, at scale. A short, genuine note to everyone who followed you this month, addressed by name, reads as a message rather than a broadcast.
In every case, the people receiving it do not need to know about each other, and most of them would rather they did not.
Why a group DM makes a poor broadcast
It is tempting to add 200 followers to one group and send your announcement once. It nearly always goes badly.
Everyone sees everyone. You have just handed your contact list to every person on it.
Replies multiply. Every "thanks" and "interested" goes to all 200 people, with a notification each time. People mute the group or leave within minutes.
It feels like a mailing list nobody signed up for. Being added to a group of strangers is a very different experience from receiving a personal message.
Invitations from people they do not follow go to requests. If someone does not follow you, being added to your group shows up as a request they have to accept, and many will not bother.
A mass DM avoids all four problems. Each person gets one message, and any reply is a private conversation with you.
How to start a group DM on X
- Open your messages and start a new message.
- Add the people you want in the group, one at a time.
- Give the group a name, so people know why they are there.
- Send a first message that explains who everyone is and what the group is for.
X's newer Chat also lets you create an invite link for a group, share it, and approve the people who ask to join. Admins can switch the link off at any time. People who have not finished setting up Chat, including its four-digit passcode, can have trouble joining encrypted groups, so if someone cannot be added, ask them to finish that set-up first.
How to send a mass DM on X
X has no built-in way to send one message to many people individually. That leaves two options.
By hand. Open each conversation, paste your message and personalise the first line. Fine for twenty people. Painful for two hundred, and easy to get wrong when you are copying and pasting names.
With a tool. The Twitter/X mass DM tool in Tweeksocial sends one personalised message to every follower you choose, or to a CSV list of handles, spread through your active hours at up to 300 a day per connected account. Replies arrive as normal private conversations. The usual rules about who can receive your messages still apply, which is why a mass DM works best on people who already follow you. The guide to why you cannot DM some people on X explains those rules in full.
Writing for each format
The message itself should change with the format.
In a group, write for the room. Say why the group exists, who is in it and what happens next: "Everyone here is speaking at the March meetup. I will post the running order here on Friday, and you can ask anything in this thread."
In a mass DM, write for one person. Use their name, keep it short and end with an easy question. "Hi Sam, I have just opened early access to the course you asked about in January. Shall I send you the details?" reads as a note. The same words in a group of 200 read as spam. Our Twitter mass DM templates include nine examples written to work one to one.
Mixing the two
The two formats also work well together. A common pattern is to send a mass DM inviting people to something, then put the people who say yes into a group.
For example, you might message everyone who follows you for your course, asking whether they would like to join a small study group. The replies come back privately, so nobody feels pressured by who else said yes. Then you add the people who want to join into one group chat, where they can meet each other and talk. Each format is doing the job it is good at.
Frequently asked questions
How many people can be in a Twitter group DM?
X raised the maximum size of a group chat to 256 people in 2023. For anything bigger, or anything where people should not see each other, a mass DM is the better choice.
Can I send one message to all my followers on X?
Not natively. A group DM has a size limit and shows everyone to everyone. To reach all your followers privately, you need to send individual messages, either by hand or with a mass DM tool.
Can people in a group DM see each other?
Yes. Everyone in a group can see who else is in it and read every message sent to the group.
Will people know a mass DM was sent to others as well?
Not unless you tell them. Each message is its own conversation, so nobody can see who else received it.
Why did someone not join my group chat?
If they do not follow you, your invitation arrives as a request they have to accept. In X's newer Chat, people who have not set up their passcode can also have trouble joining encrypted groups.
Is a mass DM the same thing as a broadcast?
Not quite. A broadcast is one message to many people in one place. A mass DM is many one-to-one messages, so each person can reply to you privately.
The short version
Use a group DM when the people in it should talk to each other, up to 256 of them. Use a mass DM when you want to reach many people privately and hear back from each one. Adding hundreds of followers to one group to make an announcement is the combination that nearly always goes wrong.
