Twitter for customer service: a practical guide to X

Twitter for customer service, now X, works best when a business acknowledges each complaint publicly within hours and moves account details to direct messages (DMs, the private inbox on X). ProfileTree, a Belfast social media and web agency, advises small teams to set reply targets they can keep and to keep personal data out of public posts.

Why customers still take complaints to X first

Customers use X for complaints because a public post puts pressure on a business in a way that an email does not. Anyone who searches your brand name can see the post and, more importantly, can see whether you answered it. A well-handled thread works as proof of good service for prospective customers, while an unanswered one sits in search results for months.

The cost of silence is measurable. In the 2025 Sprout Social Index, 73% of social media users said they would buy from a competitor if a brand did not respond to them on social media, and about three-quarters expected a reply within 24 hours or sooner. Those figures cover social platforms in general, but X is where public complaints are most visible, because replies and quote posts spread a complaint beyond the person who made it.

This is the reason support on X sits inside social media marketing at ProfileTree, alongside content and community management. ProfileTree is a Belfast web design and digital marketing agency, founded in 2011 and based at the McSweeney Centre, and the support workflow in this guide reflects what we recommend to SMEs that handle their own social accounts.

What the move from Twitter to X changed for support teams

Twitter was renamed X in July 2023, after Elon Musk bought the company in October 2022, and twitter.com now redirects to x.com. For a support team, the day-to-day job has not changed, because customers still complain in public and the support work still moves into private messages once account details are needed. Tweets are now called posts, and the blue checkmark comes with a paid subscription; X no longer awards it on the basis of an editorial review of the account.

The checkmark change matters for one practical reason. Customers can no longer assume a verified-looking account is the real business, so scam accounts that copy a brand’s name and reply to complaints are a real risk. Use your bio and a pinned post to show which handle is yours, and say plainly that you will never ask for a password or card number in a reply or a DM.

Setting up your X account for customer service

A support-ready account tells customers where to go and when someone will answer. Most of this takes an afternoon to set up and then needs a check every few months.

One brand account or a separate support handle

Most SMEs should run customer service from their main brand account. A second handle splits your followers, and customers will tag the main account anyway. A dedicated support handle starts to make sense once support replies would crowd out everything else on your main timeline, which usually means a team handling dozens of queries a day.

If you do create a support handle, link the two in each bio and pin a post on the brand account that points to the support handle. Reply from the support handle even when a customer tags your brand name, so the conversation stays in one place.

Profile, bio and support hours

Your profile image should be your logo, and your display name should match the name customers know you by. Use the bio to welcome customer queries and state the hours someone is watching, with a link to your help or contact page. A line such as “Questions about an order? Post or DM us, Monday to Friday, 9 am to 5 pm” sets an honest expectation and stops an evening complaint from becoming a second complaint about being ignored.

Direct message settings

Customers who do not follow you can only message you if you allow it. In the X settings, under Privacy and safety and then Direct Messages, switch on the option labelled “Receive messages from anyone” on Android and the web, or “Allow message requests from everyone” on iOS. X’s help pages on Direct Messages explain that messages from people you do not follow then arrive as requests, which someone on your team needs to check as often as the main inbox.

The same help pages note that media shared in a DM can be downloaded and re-shared by anyone in the conversation. Treat a DM as private from the public, though never as secure, and do not use it to collect payment details or identity documents.

A reply workflow for complaints on X

The workflow ProfileTree recommends has three stages, and the third is the one most businesses skip. Each stage has a different audience: the first and last are written for everyone reading the thread, and the middle one is written for the customer alone.

Acknowledge the complaint in public

Reply to the original post quickly, even if you do not yet have an answer. The acknowledgement only has to show that a person has read the complaint and is dealing with it, for example: “Sorry to hear this, Sarah. We are looking into it now. Could you send us a DM with your order number so we can check what happened?” Sprout Social’s Q4 2025 pulse survey found that 51% of consumers who contact a brand publicly expect a public acknowledgement before they are moved to a private message, so going straight to “please DM us” with no apology reads as a brush-off.

Keep the tone of your normal feed. A brand that posts in a friendly, informal voice and then answers complaints in stiff corporate language sounds as if it has handed the problem to someone else. Add warmth for an angry customer, but do not argue the facts in public, even when the customer is wrong.

Resolve the details in private messages

Move the conversation into DMs as soon as you need an order number or any other account detail. Ask only for what you need to find the order or the account, and answer in plain sentences without scripted phrases. If the issue needs another team, tell the customer who will contact them and by when, then make sure that person actually does it.

Many complaints need more than one channel to fix, such as a call from the accounts team or a replacement sent by post. Note the X handle against the customer record in whatever system you use to track enquiries, so the person running the X account can see when the problem has been solved.

Close the loop on the public thread

When the issue is sorted, go back to the original public post and say so, with the customer’s agreement: “Thanks for bearing with us, Sarah. Glad the replacement arrived.” Anyone who finds the thread later sees the full story, from complaint to resolution, which is far more persuasive than a complaint followed by “DM us” and silence.

Handling abusive or bad-faith posts

There is no obligation to engage with abuse. Mute or block accounts that post threats or harassment, and report them to X where they break its rules. A complaint that is angry but legitimate is different, and it deserves the same workflow as any other, with the tone set aside and the substance handled in private.

Keep a short internal note of how you handled each difficult thread. If a complaint escalates into a press enquiry or a legal letter, a record of what was said and when is the first thing you will need.

Response time targets a small team can keep

The right target is the one your team can hit every week, because customers notice an inconsistent service more than a slightly slower but reliable one. A reply within 20 minutes on Tuesday followed by a day of silence on Thursday trains customers to expect the first and then disappoints them with the second.

These are the targets ProfileTree suggests by staffing level. They are starting points for planning, not industry benchmarks, and should be adjusted once you know your own volumes.

Whichever row fits, put the hours on your profile and in any automated welcome message. A customer who knows a reply is coming at 9 am is far less likely to post a second, angrier complaint at 10 pm.

What never belongs in a public reply

A public reply on X can be copied and screenshotted by anyone, so it must never contain information that identifies a customer beyond their own handle. Under UK GDPR (the UK’s data protection law, enforced by the Information Commissioner’s Office), names combined with order details, addresses, phone numbers, email addresses and account information all count as personal data. The ICO’s guidance on what counts as personal data sets out the test, which is whether a person can be identified from the information, directly or indirectly.

In practice, train everyone who posts on the account to follow a few rules. Staff should not confirm in public that a named person is a customer beyond what that person has already said. If a customer posts an order number or delivery address by mistake, do not repeat it; ask them to delete the post and send the details by DM. Passwords, full card numbers and copies of identity documents should never be requested, in public or in private.

Businesses that serve customers in the Republic of Ireland work under the EU GDPR, which follows the same principle. If you are unsure whether a reply would disclose personal data, move the conversation to DMs before saying anything specific.

Automation and AI in X customer service

Automation is useful on X for the first reply and for sorting queries, but a person still needs to resolve the complaint. An automated welcome message in DMs can collect the order number and set expectations for when someone will reply, which saves a round of messages on every query.

AI tools can now draft replies and route incoming posts to the right person by topic or sentiment. In Zendesk’s CX Trends 2026 survey of more than 11,000 consumers and business respondents, 74% of consumers said they were frustrated when they had to repeat information, which is the strongest argument for automation that passes context to a person. A bot that collects details and then hands the customer to someone who has already read them is helpful; a bot that loops customers through menus makes the original complaint worse.

Publish nothing an AI tool has drafted without a person reading it first, because a confident wrong answer on a public thread is hard to take back. If you are weighing up automation for X and website enquiries together, ProfileTree’s AI chatbots and automated first replies service covers set-ups where a person always takes over the conversation.

Measuring customer service performance on X

Follower counts and likes say little about service quality. The figures worth tracking each month show whether customers get answers and whether their problems get fixed.

The most useful measure is the average time to first reply against the target you set, split by public mentions and DMs, followed by the share of queries resolved without the customer switching to phone or email. Count the public threads you closed with a follow-up reply as well. Read a sample of mentions every month to judge whether sentiment is moving in the right direction, because automated sentiment scores often misread sarcasm and local phrasing.

X’s built-in analytics show impressions and engagement on your posts, while social media management software adds reply times and conversation tagging. A shared spreadsheet is enough for a firm handling a few queries a week, as long as someone updates it consistently.

Once support is under control, the same account can do more than answer complaints. Our guide to building engagement on X covers communities and live audio sessions for brands, and our guide to customer service across other social platforms compares how the workflow changes on Facebook and Instagram.

“ProfileTree has more than 500 Google reviews with a 5.0 rating, and what I notice reading them is how many mention a conversation more than a deliverable. People recall being listened to, and social media marketing for a Belfast business works the same way: a customer who complains on X and gets a real reply from a real person tends to recall the reply long after the problem,” says Ciaran Connolly, founder of ProfileTree.

Getting help with customer service on social media

If replying to customers on X is falling to whoever has a spare minute, the next step is to agree the workflow, the hours and the reply targets in writing, and to make one person responsible for them. ProfileTree helps businesses in Northern Ireland, Great Britain and the Republic of Ireland plan and run organic social media management, including the customer service workflow covered here, and runs social media training for your team for businesses that would prefer to keep it in-house.
