7 Best InboxApp Alternatives for X (Twitter) and LinkedIn in 2027

InboxApp is a fast DM inbox and lightweight CRM for X (Twitter), with LinkedIn in the same inbox. It is good at one job: answering the conversations you already have, with tags, statuses and a simple pipeline.

Teams look for an InboxApp alternative when they need new conversations. That means finding leads on X, sending cold DMs from several accounts and letting AI answer the replies. On InboxApp, lead generation and automations are part of the Pro plan, which is priced on request.

Short answer: choose ReachHunt if you sell on X and LinkedIn and need new leads. It adds a 500M+ X profile database, DM workflows, email and AI agents to the inbox and pipeline. For X-only cold DMs, look at XReacher or DMpro. To sell to your own followers, use Tweet Hunter. For a faster inbox without outreach, try Kondo.

How we compared: we read each tool’s website, pricing page and help docs in November 2026 and noted what each one lists for X, LinkedIn, lead finding, outreach and the inbox. When a site doesn’t mention a feature, we write “not listed” instead of “no”. ReachHunt is our product, and features change often, so check each vendor’s site before you buy.

Why teams look for an InboxApp alternative

InboxApp calls itself “Superhuman for X”: a DM client and lightweight CRM for people whose business runs on X. Its Basic plan includes one seat, one linked account per platform, tags, statuses, a pipeline, a public API, MCP and webhooks, with a 7-day free trial. Lead generation, automations, unlimited linked accounts and team collaboration are on Pro, which has custom pricing.

The reasons people outgrow it usually come before the first message:

• They need new leads on X. An inbox shows the people who already talk to you. Outbound teams need lists of new people, like every founder in London with a real audience, or the followers of a competitor.
• They want cold DM campaigns on every plan. Teams that send DM sequences with follow-ups from day one look for a tool where outreach is included.
• They have several senders. Agencies and sales teams need room for every account and every teammate who answers.
• They do LinkedIn outreach too. Connection requests, follow-ups and InMail need an outreach engine on top of a LinkedIn inbox.
• They want AI to reply. An AI agent can answer common questions around the clock and hand hot leads to a person.

What to look for in an InboxApp alternative

1. Lead sources. Can you search X profiles by bio, location and audience size, or import followers, post engagers and X lists?
2. Outreach. Does it send personal DM sequences from several accounts, with follow-ups that stop when someone replies?
3. Inbox and CRM. Do replies from every account land in one inbox with tags, notes and a pipeline your team shares?
4. Networks. X only, LinkedIn only, or X, LinkedIn and email in one workspace?
5. AI. Can AI write messages, answer replies and hand over to a person?
6. Account care. Does it warm up new accounts and send at a human pace?
7. Integrations. Is there a REST API, webhooks, CRM sync or an MCP server for Claude and ChatGPT?
8. How you pay. Per seat, per sender account or by volume?

The 7 best InboxApp alternatives in 2027

1. ReachHunt

Best for: sales teams, founders and agencies that sell through DMs on X and LinkedIn and want finding, sending and replying in one workspace.

ReachHunt covers the path from a stranger to a booked call, and it starts where an inbox can’t: finding the right people. The X (Twitter) database holds 500M+ public X profiles you can filter by bio, location, followers, following, post count, verified type, website, name and username. A Can DM filter keeps the people whose DMs are open to you. You can also fill a lead list from the followers of any account, the people who liked, reposted or replied to a post, X list members, LinkedIn searches, groups, post engagers and connections, or a CSV.

Then you build the outreach in a visual workflow builder. On X, a workflow can visit a profile, follow, like or retweet a recent tweet, reply to one and send the DM. It can branch on questions like “Followed you back?”, “Read your DM?” or “Accepts DMs from anyone?”. On LinkedIn it can visit, connect, message, send free InMail to Open Profiles, like a recent post, follow and endorse skills, with branches such as “Accepted your request?” and “Has LinkedIn Premium?”. Anyone who replies leaves the workflow, and every reply lands in one inbox and pipeline your whole team shares. An AI agent can answer there in your voice and hand the chat to a person when it matters.

Pros

• A 500M+ X profile database with filters you can stack, plus 22 ways to fill a lead list across X, LinkedIn and CSV
• Twitter DM automation with a workflow builder: a follow or a like before the DM, Yes/No branches, follow-ups that stop on reply, and message variations or AI-written messages
• X, LinkedIn and email outreach in one workspace
• One inbox for every account, with tags, notes, chat assignment, scheduled messages and a pipeline where every conversation is a deal card with a value
• AI agents trained on your company that work toward a goal like booking a call, follow your guardrails and hand over to a person
• Auto-translate for conversations in 133 languages, sent inside the hours you set
• Warm-up, smart limits and human-paced sending on by default, plus auto-withdraw for old LinkedIn invites and your own proxies if you want them
• HubSpot, Pipedrive, Clay, Smartlead and n8n, plus a Twitter DM API, webhooks and an MCP server for Claude, ChatGPT and Cursor

Cons

• It covers X, LinkedIn and email. WhatsApp and Telegram chats aren’t part of it.
• It is built for outreach, so you won’t find post scheduling or growth analytics. Pair it with a content tool if you need those.

Pricing model: per connected account, not per seat, with unlimited teammates and unlimited campaigns. There is a 14-day free trial with no card required.

Choose it if you want to find and message new people on X and LinkedIn, and answer them in the same place.

2. XReacher

Best for: agencies, coaches and startups that run cold DM campaigns on X across many accounts and want LinkedIn and Telegram on the same plan.

XReacher calls itself “the DM automation tool for agencies, coaches & startups”, with X, LinkedIn and Telegram outreach under one subscription. Its built-in scraper pulls leads from an account’s followers or following, or from the people who liked, commented on or retweeted a tweet. You can filter them by bio keywords, location, follower ranges, verified status, website and closed DMs. Campaigns rotate several accounts, can follow before they DM and send follow-ups on your own delays. Replies land in one inbox, where an AI reply agent can answer.

Pros

• X, LinkedIn and Telegram on one subscription
• A built-in lead scraper with bio, audience and closed-DM filters
• Follow-before-DM, follow-up sequences and several accounts, each with its own proxy
• One inbox with an AI reply agent and quick-reply templates
• A done-for-you option where their team sets up and warms up your accounts

Cons

• Its FAQ asks for X Premium and an X account at least six months old
• Tags, a pipeline and team seats are not listed on its site (its “seats” are connected accounts)
• A public API and webhooks are not listed
• The free trial asks for a card

Pricing model: per connected account, counted per platform, with a 7-day free trial on Pro.

Choose it if you run X cold DMs across many accounts and also want Telegram.

3. DMpro

Best for: solo founders and small teams who sell only on X and want cold DMs to run on autopilot.

DMpro is built for automated cold DMs on X (Twitter). It pulls leads from the followers of an account, members of an X community, people who replied to a tweet or to tweets with your keywords, a bio keyword search, or your own CSV. A drag-and-drop workflow (wait, send a DM, check for a reply) does the sending, and AI personalizes each message from the person’s bio, recent posts and website. Leads sit in a Lead Base with statuses such as new, contacted and replied.

Pros

• Lead scraping from followers, communities, tweet replies and bio keywords
• AI personalization that goes beyond the first name
• Visual sequences with follow-ups and campaign analytics
• A done-for-you option where their team runs the outreach

Cons

• X only, so LinkedIn needs another tool
• A shared team inbox is not listed: the site focuses on sending and lead management

Pricing model: by the number of X accounts, with a daily DM allowance per account and a 7-day money-back guarantee.

Choose it if you work alone on X and want cold DMs with AI personalization.

4. Tweet Hunter

Best for: creators and founders who sell to their own audience on X.

Tweet Hunter is an X growth tool with AI writing, scheduling, analytics and automation. Its Auto DM messages people who interact with your tweets, so a “reply to get the guide” post delivers the guide by itself. Its CRM features help you find relevant tweets, pull the people behind them and reach out.

Pros

• AI tweet and thread writing, scheduling and analytics
• Auto DM for people who engage with your tweets
• Auto retweet and auto plug
• CRM features to find and contact people from relevant tweets

Cons

• X only
• Built around audience growth more than cold outreach to new lists

Free trial: 7 days.

Choose it if your leads come from your own content and followers.

5. La Growth Machine

Best for: B2B teams that run LinkedIn and email sequences and want an X touchpoint.

La Growth Machine (LGM) puts LinkedIn, email, LinkedIn voice messages and call tasks in one sequence, with conditions, branches and A/B tests. Its X step follows the lead on X and sends a DM inside the same sequence. Replies from LinkedIn and email land in a shared inbox where you tag them as Interested, Call Booked and more, and LGM syncs both ways with HubSpot and Pipedrive.

Pros

• LinkedIn, email, voice and call steps in one sequence, with branches and A/B tests
• X follow and DM steps
• A shared inbox with reply tags and two-way HubSpot and Pipedrive sync
• An MCP server, a Reply Agent in beta, an API, and Clay, Zapier, Make and n8n on its Pro plan

Cons

• X is one step inside a LinkedIn and email sequence, and finding leads on X is not listed
• The shared inbox is listed for LinkedIn and email replies

Pricing model: per sender identity, your whole team joins free, and there is a 14-day free trial.

Choose it if your lists start on LinkedIn and email, and X is an extra touch.

6. Meet Alfred

Best for: LinkedIn-first sales teams and agencies that want X DMs in the same campaign.

Meet Alfred is one of the original LinkedIn automation tools, and it runs multichannel sequences across LinkedIn, email and X (Twitter). On X it can send personalized DMs, follow lead profiles and schedule posts. Its Smart Inbox lets you read, label and archive conversations and keep notes on each lead, and teams get roles, shared team inboxes and team-level reporting.

Pros

• Multichannel sequences across LinkedIn, email and X
• X DMs and automatic follows inside campaigns
• Smart Inbox with labels and notes
• Team roles, shared inboxes and reporting

Cons

• Lead finding is built around LinkedIn, so X works as a channel inside LinkedIn-led campaigns
• Zapier and webhooks start on the Business plan

Choose it if you already prospect on LinkedIn and want X as a second channel.

7. Kondo

Best for: people who live in their LinkedIn and WhatsApp DMs and want the fastest possible inbox.

Kondo calls itself “Superhuman for DMs”. It is a keyboard-first inbox for LinkedIn, WhatsApp, iMessage and Telegram, with labels, split inboxes, snippets, snooze and reminders, notes, filters and automatic voice note transcripts. It syncs work chats to HubSpot, Salesforce, Attio and more, and its MCP server lets Claude, ChatGPT or Cursor work your DMs. Your inbox lives on your computer, and Kondo never sees your password. InboxApp publishes its own comparison page against Kondo, which makes Kondo its closest rival as a pure DM inbox.

Pros

• A fast, keyboard-first inbox with split inboxes, snippets and reminders
• LinkedIn, WhatsApp, iMessage and Telegram in one place
• CRM sync and an MCP server

Cons

• X is not among its live platforms
• Kondo says it does not automate, so campaigns and lead finding are not part of it

Refunds: Kondo offers a no-questions-asked refund.

Choose it if you only want a faster inbox and X isn’t your main channel.

Other InboxApp alternatives we looked at

• Circleboom: an X management suite with Smart Account Search (bio keywords, follower counts, join dates and verified status), follower analytics, a post planner and X outreach workflows. Strong for finding and managing X accounts, lighter as a sales inbox.
• SuperX: a Chrome extension that adds a growth dashboard, AI writing, scheduling, analytics and auto DM for people who engage with your posts. X only, and free to start.
• Beeper: a free chat app that puts WhatsApp, Telegram, Signal, X, LinkedIn, Slack and more in one inbox. It is built for personal messaging, so it has no sales features.

How to find leads on X (Twitter) when an inbox isn’t enough

An inbox only shows people who already talk to you. To grow, you need a steady list of new people who fit your buyer. There are four common ways to build one on X:

1. X advanced search. Free and good for finding posts about a topic. It searches posts rather than people, so you can’t filter by bio, location and follower count at the same time.
2. Followers, engagers and lists. Import the followers of a competitor, everyone who liked, reposted or replied to a post, or the members of an X list. Great for warm audiences, though each import only covers one account or post.
3. Bio search tools. Circleboom and DMpro let you search X bios by keyword, and XReacher filters scraped audiences by bio. Followerwonk (now part of Fedica) does bio search for analytics and exports.
4. A profile database built for outreach. The ReachHunt X Database lets you search 500M+ public X profiles with stacked filters and add the people who fit straight to a lead list and a workflow.

Example searches you can run in the X Database, each with a few filters:

• Founders in London with a real audience: bio contains “founder”, location contains “London”, more than 1,000 followers
• Companies hiring sales reps: bio contains “hiring” and “SDR”
• Verified fintech businesses: verified type is Business, bio contains “fintech”
• US agency owners with a website: bio contains “agency”, website is not empty, location contains “USA”
• Active Web3 developers: bio contains “Solidity”, more than 500 posts
• Marketing leaders: bio contains “CMO”, more than 5,000 followers

Add the matches to a lead list, keep the people whose DMs are open with the Can DM filter, and start a workflow. The Twitter user database page shows every filter.

InboxApp vs ReachHunt

If you are deciding between staying on InboxApp and moving to ReachHunt, here is the short version (checked in November 2026).

Stay on InboxApp if you mainly need a fast inbox for conversations you already have. Move to ReachHunt if you need new ones: finding people on X and LinkedIn, reaching them with workflows and email, and letting AI handle the replies.

Which InboxApp alternative should you choose?

• You sell on X, or on X and LinkedIn, and need new leads: ReachHunt.
• You run cold DMs on X across many accounts: XReacher, or ReachHunt if you also want the X Database, a pipeline and email.
• You work alone and only send cold DMs on X: DMpro.
• You sell to your own followers: Tweet Hunter, or SuperX if you want it inside X.
• Your outreach starts on LinkedIn and email: La Growth Machine or Meet Alfred, or ReachHunt if X matters as much as LinkedIn.
• You only need a faster inbox: Kondo for LinkedIn and WhatsApp, Beeper for a free all-in-one chat app, or stay on InboxApp.
• You run outreach for clients: ReachHunt, with a workspace per client and connect links so clients bring their own accounts.

How to switch from InboxApp to ReachHunt

1. Connect your accounts. Add your X and LinkedIn accounts with the browser extension, so you never share a password. Clients can connect their own accounts with a one-time link.
2. Bring your leads. Upload a CSV of the people you track today, or build new lists from the X Database, followers, post engagers, X lists and LinkedIn searches.
3. Recreate your tags and stages. Set up the pipeline stages you use for deals, so every conversation keeps its place.
4. Build your first workflow. Start with a follow or a like, add the DM, and branch on whether they followed you back or read your message.
5. Train your AI agent. Paste your company and product details, set its goal and guardrails, test it in a chat, then turn it on for the accounts you choose.
6. Run both for a week. Keep your old inbox while your first workflow warms up, then move your team over once replies start landing.

ReachHunt has a 14-day free trial with no card required, and you can connect your first account in about two minutes.
