How to collect emails from Facebook group members
Facebook gives group admins exactly one sanctioned place to ask a member for their email address, and it is open for about ten seconds per person. Here is how to use it, what to say, and where the answers should end up.

The short version
- The membership question at the join request is the one place Facebook lets you ask.
- It captures new members only. Existing members need a pinned post or a form.
- Name the deliverable in the question. “What’s your email?” performs worse than a promise.
- The answer is visible until you approve the request, then it is gone.
- Send the first email the same day, or the person will not remember asking.
Why the membership question is the whole game
A Facebook group is somebody else’s property. You can lose the group, the reach, or the account, and none of those events come with a warning email. An address list is the one part of the audience you can take with you, which is why admins keep asking how to get one out of a group.
Facebook’s answer is narrow. There is no member export, no lead form for groups, and no API that hands over addresses. What there is: up to three membership questions, shown to a person at the moment they ask to join, answered voluntarily, in their own words. That is the sanctioned route, and it is a good one, because a person who types their address into a box while asking to join your group is about as warm as a lead gets.
What that route does and does not cover
| Situation | Does the question help? |
|---|---|
| New join requests | Yes. This is exactly what it is for. |
| Members already in the group | No. They never saw a question. Ask in a post instead. |
| Members who joined before you enabled questions | No. Same problem. |
| People invited directly by another member | Usually not. Invited joins can bypass the question. |
| Members of a group you do not admin | No, and nothing legitimate will. |
Scroll for the rest
So this is a forward-looking play. Turn questions on today and you start collecting tomorrow’s members. For the people already inside, the honest answer is a pinned post with a link to a form and a reason to click it. Slower, still works.
Wording the question
You get three questions and you should spend one of them on the email. What you write in that one box does more for your results than any tool you bolt on afterwards.
The version that underperforms
“What is your email address?” Nothing is offered, nothing is explained, and the person has no idea what arrives next. Some people answer it anyway. A meaningful number type a fake address, and a fake address is worse than a blank one, because it looks like a win in your sheet and bounces two days later.
The version that works
Name the thing, name the frequency, and give an exit:
Copy this and swap the noun
“What’s the best email for you? I’ll send the 12-page group setup checklist straight away, then one short post a week. Happy to leave this blank if you’d rather just read the group.”
Three sentences, doing three jobs. The first asks. The second says exactly what lands in the inbox and how often, which is both a promise and your record of consent. The third gives permission to skip, which sounds like it costs you addresses and instead costs you the fake ones.
Two more rules for the wording
- Deliver something they cannot get inside the group. If the checklist is also pinned in the feed, the address buys them nothing.
- Keep it short. The question box is not generous with space, and it is read on a phone, in a hurry, by someone who wanted to be in the group already.
What to offer
The offer should be the thing the group is about, compressed. A few that suit the format, because they are quick to consume and obviously useful:
- A checklist that covers the thing every new member asks about in week one.
- The template, spreadsheet or swipe file you already built for yourself.
- A short recording that answers the question the group asks most often.
- A calculator or pricing sheet, if your niche argues about numbers.
What does not suit the format: anything long, anything gated behind a second form, and anything that reads as a sales page. The person has not bought anything yet. They asked to join a group.
Where the answers go
The answer is only visible on the pending request card, and it disappears when you approve or decline. That constraint drives the whole workflow, and it is covered in detail in the guide on saving question answers. The short version: get the row into a sheet before you touch the approve button.
- 1
One row per request, written before approval
Timestamp, name, profile URL, the three answers, and which group it came from.
- 2
Validate the address on the way in
Trailing spaces and obvious typos are cheap to fix at this point and expensive later.
- 3
Send the promised thing the same day
Delay it by a week and the recipient has forgotten the group, the question and you.
- 4
Then approve
The member arrives having already received something useful, which is a considerably better first impression than a welcome post.
The first email decides the list
One email, sent within the hour, containing the thing you promised and nothing else. No offer, no calendar link, no second ask. It should read like it came from a person who keeps their word, because that is precisely what it is proving.
Put the group name in the subject line. People do not remember your name yet, they remember the group they just asked to join. “Your checklist, from [group name]” gets opened. “Welcome!” does not.
Approaches that waste your time
- Asking for emails in a post. Public addresses in comments get scraped by everyone reading the thread, and Facebook’s feed will show your post to a fraction of the group anyway.
- Messaging new members individually. It does not scale past a few a day, and volume messaging is a fast route to a restricted account.
- Anything that claims to extract member emails in bulk. Facebook does not expose them. A tool promising otherwise is either lying or is going to get your account actioned.
Keeping the list clean
Record the question wording and the date next to every address. When your email platform asks how the list was collected, or a subscriber asks why they are hearing from you, the answer is a cell in the same row rather than a memory. Store the group name too. The day you run three groups you will want to segment by which one someone came from, and retrofitting that column is miserable.
None of this is legal advice. If you operate under GDPR or an equivalent regime, the practical habit that keeps you out of trouble is boring and effective: keep the evidence of what you asked, and only do what you said.
Doing it without the manual step
The whole sequence above is mechanical: read the card, write the row, send the email, approve the member. That is what this category of tool automates, and the comparison page covers who does which part. The difference worth checking before you pick one is whether the tool needs your browser sitting open on Facebook while it works.
Questions people ask
- Can I get the email addresses of people already in my group?
- Not from Facebook. Membership questions are only asked at the join request, so they capture new members only. For people already inside, the options are a pinned post with a link to a form, a welcome post that asks, or a lead magnet offered in the feed. All of them are opt-in and none of them are automatic.
- Is collecting emails through membership questions allowed?
- Asking is the intended purpose of the feature, and the person types the answer themselves. The conditions that matter are the ones you set: say in the question what the address will be used for, do only that, and make it easy to leave the field blank. Harvesting addresses people did not volunteer is a different activity and is not permitted.
- How many members will actually give me an email address?
- It depends on your group and your wording, and we are not going to quote a benchmark we have not measured. What is worth knowing is the shape of the change: questions that name a specific deliverable get more usable addresses than questions that just ask for an email, and a question people can skip gets fewer addresses but better ones.
- Do I need double opt-in for addresses collected this way?
- Your email platform's rules and your local law decide that, not us. Many platforms treat an address typed into a third-party form as a single opt-in and will accept it with a clear source note. If you operate under GDPR, record the question wording and the date alongside the address so you can show what the person agreed to.
- What is the fastest way to lose a list built this way?
- Sending something the question did not promise. If the question said a checklist and one post a week, the person who receives a daily promotion marks it as spam. That one action costs more than the address was worth.
