The Twitter Unfollow Whitelist: Who to Protect Before You Clean Up

A whitelist is a list of accounts that an unfollow tool will never touch, whatever its rules say. Build it before the first run, put everyone in it whose removal you would regret, and the rest of the clean-up becomes low risk.

It is the least glamorous part of any auto unfollower and the one that saves the most trouble. Rules can be tuned, paces can be lowered, and a removal can be undone with a click. What cannot be undone is the moment a customer notices that you stopped following them, or a journalist you were hoping to hear from sees that you left.

This guide lists the groups worth protecting, shows a quick way to build the list, explains where the whitelist and the mutual-follower setting each fit, and covers how to keep it up to date.

Why a whitelist matters more than any other setting

An unfollow rule works on patterns. It sees an account that has not followed back after a week, or has not posted in six months. It does not know that the account belongs to a client who never uses the app, or a mentor who reads but does not follow, or a competitor whose launches you need to see.

People are not patterns. The few who break the pattern are exactly the ones who matter. A good whitelist is the place where your own knowledge overrides the rules.

There is a second benefit. Knowing that the important accounts are safe lets you run the rules more confidently, and that usually means you run them at all. People without a protected list tend to postpone cleaning up indefinitely, because the worry about one wrong removal outweighs the benefit of the clean-up. The problem this causes, a ratio that keeps drifting downwards, is described in the guide to the follower-to-following ratio.

The seven groups to protect

Go through these in order. Most accounts have people in at least five.

1. Customers and clients. Anyone who pays you, or has paid you. A paying customer who sees an unfollow may read it as a change in the relationship, whatever you intended.

2. Partners and collaborators. People you work with on projects, podcasts, newsletters or launches. Many of them follow you less often than you follow them, which is exactly what a non-follower rule is looking for.

3. People who reply to you. Anybody who has taken the time to answer a post of yours is a real contact. Even one reply is a sign of attention, and attention is the scarcest thing on the platform.

4. Journalists, editors and podcast hosts. They follow few accounts and read many. A one-way follow of a journalist is normal and is not a reason to remove them.

5. Mentors and people you learn from. Large accounts almost never follow back. If you follow somebody whose work you rely on, protect them, or the rule will remove them first.

6. Competitors and peers you watch for work. Not everyone you follow is a friend. If you follow a competitor to see what they launch, the account will qualify as a non-follower for ever.

7. Close friends and family. They should not need to be on a list, and yet the one person who fails to follow back is invariably the one who asks about it.

A short test for borderline cases: if somebody asked why you stopped following this account, would you be embarrassed? If so, add it.

Build the list in twenty minutes

You do not need to review thousands of accounts. A quick pass is enough.

1. Start with your direct messages (five minutes). Anyone you have exchanged messages with is a contact. Scroll through recent conversations and note the names.
2. Check your lists and bookmarks (three minutes). If you keep lists of customers, peers or sources, every account on them goes on the whitelist.
3. Review who replies (five minutes). Open your notifications and scroll back through the last few weeks. Everyone who answered a post is a candidate.
4. Add the obvious one-way follows (five minutes). Think of the large accounts you follow for their work. You will remember most of them within a minute.
5. Look at the preview (two minutes). Before the first run, check the list of accounts that the rules would remove. Anyone on it that you recognise belongs on the whitelist. This step catches the people you forgot.

In Tweeksocial's auto unfollow you can import a list or pick accounts by hand, so a spreadsheet of customer handles goes in at once.

Where the mutual-follower toggle fits

Tweeksocial has a single switch that protects mutuals, meaning everyone who follows you and whom you follow. It is worth turning on, and the reason is easy to miss.

The non-follower rule never matches a mutual, because a mutual follows you back by definition. But the other rules can. An inactivity rule removes anybody who has not posted for a set number of days, and a keyword rule removes anyone whose bio lacks a word. Either can match somebody who follows you and simply goes quiet.

Protecting mutuals means a friend who stopped posting for a year is not cleared out alongside the dormant strangers. It does not replace the whitelist, though. The whitelist exists for the one-way follows, such as the mentor, the journalist and the customer who never opens the app.

What to leave off the list

The aim is a short list of people who matter, not a long list of everyone you might like.

If you protect hundreds of accounts you hardly remember, the clean-up has less to work on and the ratio improves more slowly. A reasonable size for a personal account is somewhere between twenty and a hundred names, plus the mutuals toggle. A business with many customers may have more, and that is fine.

Do not add accounts out of guilt. If you do not recognise a name and have no reason to follow them, the clean-up is the right tool. For suspicious accounts specifically, see the guide to removing bot followers.

Whitelists for client accounts

If you manage accounts for other people, the list is the most valuable thing you build for each one.

The people a client must never lose differ completely from client to client: their customers, their investors, their partners, the journalist who covers them. You cannot guess these from outside, and a whitelist copied from one client to another is wrong for both.

Ask each client for the names in their first week, and keep a separate protected list for every account. Agencies that do this stop most unwelcome surprises before they start. The approach is covered in the guide to Twitter automation for agencies.

Keep it current

A whitelist is not finished when you build it. People join it, and people leave it.

Review it every quarter. Scroll through the list. Remove accounts you no longer care about, and add new customers, partners and contacts from the last three months.

Add people when the log surprises you. Every removal is logged with a reason and a time. If you see a name you did not expect, add it to the list and re-follow the person with one click. The settings that make this routine are covered in Twitter auto unfollow settings.

Add new contacts as you meet them. After a good conversation or a new client signs, add them the same day. Habits last when they take ten seconds.

Frequently asked questions

What is a whitelist in a Twitter auto unfollower?

It is a list of accounts that the tool never unfollows, whatever the rules say. It lets you override the automatic rules for the people you know matter.

How many accounts should be on the list?

For a personal account, twenty to a hundred is usual. A business with many customers may have more. The list should hold the people whose removal you would regret, not everyone you follow.

Do I need a whitelist if I only unfollow non-followers?

Yes. A non-follower rule is the one most likely to match the people on the list above, because mentors, journalists, customers and large accounts rarely follow back.

What does protecting mutuals do?

It stops accounts that follow you from being removed by the inactivity or keyword rules. The non-follower rule never matches mutuals anyway, but the other rules can.

Can I add accounts after the clean-up has started?

Yes. Add them whenever you like. The sooner you add somebody the better, because a removal that has already happened has to be reversed by following them again. Whether they notice is covered in what X tells someone when you unfollow them.

What if I removed somebody by mistake?

Follow them again from the log, and add them to the list so it cannot happen twice. Most people do not notice a short gap, but do not repeat it.

The summary

Protect customers, partners, people who reply, journalists, mentors, competitors you watch and the people close to you. Build the list in twenty minutes, turn on mutual protection, check the preview for anyone you forgot, and review it every quarter.

A good whitelist turns auto unfollowing from something you worry about into something you can leave running.
