3 Heymarket Alternatives for CRM Texting and AI Follow-Up
Evaluate Carly as a Heymarket alternative for AI follow-up and booking, Textline for structured team texting, and respond.io for conversations spanning messaging channels. If your reason for leaving is a CRM integration, first identify the exact action that fails: selecting a number, matching a contact, assigning an owner or recording the outcome.
“Integrates with our CRM” is too broad to settle this purchase. A connection can successfully sync a contact while leaving the team uncertain about who should reply. Another can record every text but not update the business event that matters, such as a booked consultation.
This guide is published by Carly. It is based on public product documentation and original reviews checked November 9, 2026, not a head-to-head trial. We include reasons to keep Heymarket and costs that can change the apparent value of an alternative.
A customer review points to expectations worth testing
Rebecka M., an IT director, rated Heymarket 4.5/5 in an April 15, 2026 G2 review. She praised training, support and several communication features, but said the HubSpot integration “doesn’t work as expected.” The review was marked incentivized through a G2 invitation. She also raised a concern about billing beginning before training.
The wording does not explain which HubSpot action disappointed her. It would be unfair to turn it into a claim that Heymarket’s integration does not work. Another reviewer, Micah C., gave Heymarket 5/5 in an organic March 8 review and described useful coordination of shifts and use of an existing helpline number.
The practical lesson is to write down the expected behavior before the demonstration. A seller cannot prove your CRM workflow by showing a different customer’s happy path.
What Heymarket documents about HubSpot
Heymarket’s HubSpot integration guide describes sending and receiving texts in HubSpot and incorporating messages into workflows. It requires a paid Heymarket team and shared inbox and states that the integration is supported in North America.
Its quick-start documentation also explains phone-property selection, user mapping, contact-sync direction and activity-history settings. Those configuration choices can affect what staff see. Check them before assuming a missing activity means a replacement is necessary.
For example, a team may use one field for a customer’s office number and another for a mobile number. Selecting the wrong field can undermine the workflow even when the connection itself is functioning. Make that distinction part of the trial.
Heymarket pricing: include the minimum purchase
Heymarket’s pricing page lists annual-billed Standard at $49 per user/month, Plus at $99 and Pro at $199, with a two-user minimum. A 1,000-credit bundle is listed at $30/month. Incoming and outgoing SMS segments both consume credits; a segment is not always an entire message.
Two Standard seats plus that bundle therefore illustrate $128/month before other charges and configuration differences. This is a calculated annual-billing equivalent, not a month-to-month quote. If you need multistep time- or event-based workflows, check Plus rather than pricing the requirement against Standard.
For a solo operator, the minimum matters more than the one-seat headline. For a larger organization, the workflow tier and traffic may matter more than the minimum. Ask for one quote that includes the exact integration, users, numbers and usage you intend to deploy.
Shortlist the alternative by the missing outcome
| Product | Useful reason to evaluate | What the demonstration should prove |
|---|---|---|
| Carly | AI handles routine inquiries and calendar follow-up | Correct qualification, appointment and escalation |
| Textline | People need clear texting ownership and controls | Assignment, permissions and history across a handoff |
| respond.io | Messaging spans several customer channels | Contact continuity and the right workflow across channels |
These are editorial fit judgments, not rankings derived from customer satisfaction scores or delivery tests.
1. Carly: for the task after the CRM message
Carly combines AI agents with email, calendar, phone and messaging work. You can set specific rules for responses and actions, and use Carly inside ChatGPT, Claude, Grok Bot, Meta Muse or Perplexity. Carly connects to thousands of apps.
The strongest reason to evaluate Carly is a task that currently needs an employee after every incoming message. A prospective customer asks whether your service is suitable, needs a few details clarified and wants to arrange a call. The desired outcome is an appropriate appointment with context, not merely a new activity on a contact timeline.
Define the first workflow around one offer. Give the agent approved answers, the criteria for an introductory call and the correct calendar. Specify when it should ask a follow-up question and when it should hand the conversation to the account owner. Avoid rules that encourage it to guess missing commercial terms.
Then introduce a CRM complication: an existing customer uses a different number, or two contacts share a business phone. Ask the implementation team to demonstrate how the proposed setup handles the ambiguity. Do not assume any product can safely merge identities from a name alone.
Price the entire Carly setup
Free Zapier-style workflows; AI agents from $35/month. Organization seats are $35 per seat/month. Business SMS, calling and the AI receptionist are separate add-ons, and AI usage can affect the plan required.
That is not a claim that Carly provides the same messaging bundle for $35. Request a quote for the agent work, team access and communications volume together. If you need a specific CRM field changed or a particular ownership rule enforced, demonstrate that action with your account permissions.
Carly is also not a blanket substitute for every shared-inbox control. Keep a dedicated team workspace if it remains the best place for staff-led service. The Carly CRM overview explains the customer-record context behind its communications approach.
2. Textline: when people need a clearer texting process
Textline’s plans distinguish Essentials from Pro through agents, credits, retention and controls. Essentials lists three agents and three years of history; Pro lists five agents, unlimited history and more advanced roles and routing. Obtain a current quote for the plan and traffic you need.
Textline is worth evaluating if the team wants to keep people at the center of the conversation and improve assignment discipline. The decisive case is a customer moving between departments without losing the history of what was promised.
Give the vendor a sample exchange that begins in sales and becomes a service issue. Have one employee assign it, another respond and a manager inspect the record. Check whether staff can tell who owns the next action and whether the appropriate people can access the history.
Then test a manager who only needs occasional access. Include that user in the price if the operating model requires it. A plan that looks affordable with three active agents can change once supervisors and backup staff need seats.
Textline is a less direct answer if your main goal is to have an AI complete routine scheduling conversations. In that case, require an explicit demonstration of the agent behavior rather than inferring it from automation or integration terminology.
3. respond.io: when SMS is one part of the conversation
respond.io pricing lists Starter at $79/month with annual billing and Growth at $159. Growth includes workflows and AI agents. Its pricing also uses monthly active contacts, while WhatsApp fees are separate.
This makes respond.io relevant when the missing outcome is continuity across messaging channels. A customer might begin on WhatsApp, return through another supported channel and expect the team to remember the earlier exchange. That is different from simply needing a lower SMS seat price.
For the demonstration, include a customer with incomplete or conflicting profile details. Ask how the team identifies the person, reviews the prior discussion and routes the next response. Verify the actual supported channels and account setup for your business.
Budget using the people who interact, not just the number of messages. A campaign that reaches many new contacts can affect a monthly-active-contact allowance differently from a small group having long conversations. Ask how the vendor counts the exact pattern you expect.
Our respond.io alternatives guide covers this broader messaging decision. If your customers overwhelmingly use SMS and the team is comfortable in its CRM, a cross-channel platform may add more change than you need.
Four CRM cases to run before signing
Use a small, deliberate set of examples rather than an enormous feature checklist:
- Two phone fields: send to the intended mobile number and verify where the reply appears.
- A changed owner: reassign the customer, then receive another message and inspect responsibility.
- An existing customer with a new number: preserve context without silently combining the wrong records.
- A booked appointment: check the calendar, customer record and any follow-up queue for a consistent outcome.
These are proposed acceptance cases. Agree with the vendor on the intended result before testing, so a workaround is visible rather than mistaken for a supported automatic process.
Include permissions in the exercise. An integration installed by an administrator can behave differently for an employee with restricted access. The people who will use the workflow should participate in the trial.
Switch only after assigning a source of truth
Decide which system owns each type of information: contact identity, conversation history, customer status and appointments. If two systems can update the same field, establish which change wins and who reviews conflicts.
Before cutover, export the permitted records and preserve suppression status. Record active automations and scheduled sends. A successful number transfer does not prevent duplicate messages if the old follow-up workflow remains enabled.
Keep a small reconciliation list during the first week: messages with no owner, contacts with conflicting numbers and appointments that appear in only one system. Resolve those before expanding automation to more teams.
For a Carly setup call, bring the CRM handoff that currently creates the most manual work. Ask to see a routine booking and an ambiguous case, with the final customer record visible. That gives you a concrete basis for choosing between improving Heymarket and changing products.
Demonstrate the CRM handoff before you switch
Bring one customer inquiry, your ownership rules and the calendar outcome your team needs.
Help me connect Carly Teams so I can work with my organization's business texts, phone calls, voicemail and voice/text agents from this chat. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If a step doesn't match what I see, ask me what's on my screen. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Don't tell me it's connected until list_phone_lines works, and if I have several teams, ask which to use. Before sending a text or making a call, confirm the team, recipient and message or task with me. The steps are below.
# Connect Carly Teams to an AI app
> Carly Teams works a team's business phone lines through the team's AI agents: business texts, phone calls, voicemail, the voice and text agents, and the team's CRM.
MCP server: https://carlyassistant.com/team/mcp (streamable HTTP, OAuth)
## Setup
Carly Teams isn't in any plugin or connector directory yet, so it's added as a custom connection by URL.
1. Add Carly Teams:
- ChatGPT: open https://chatgpt.com/plugins, click Add, and choose Create MCP App (not Create plugin or Upload plugin archive). If Create MCP App isn't on the menu, turn on Developer mode first in Settings > Security and login. Name it "Carly Teams" with the description "Work with my team's business texts, calls, voicemail and voice/text agents," paste https://carlyassistant.com/team/mcp as the server URL, choose OAuth, create it, and sign in. Then in the message box open the + menu, choose Developer mode, and pick Carly Teams. No plugin needs to be built, packaged or uploaded.
- Claude (claude.ai, Claude Desktop, or Cowork): Customize > Connectors > Add custom connector, name it Carly Teams, paste https://carlyassistant.com/team/mcp, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly-teams https://carlyassistant.com/team/mcp`, then /mcp, pick carly-teams, and authenticate.
- Codex: `codex mcp add carly-teams --url https://carlyassistant.com/team/mcp`, then `codex mcp login carly-teams`.
- Cursor: add {"mcpServers": {"carly-teams": {"url": "https://carlyassistant.com/team/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly-teams from Customize.
- Muse: a custom connector to https://carlyassistant.com/team/mcp with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly Teams) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/team/mcp, and sign in.
- Grok Bot: a custom remote MCP server named carly-teams at https://carlyassistant.com/team/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly Teams, paste https://carlyassistant.com/team/mcp, pick OAuth, check the box and click Add, then click the Carly Teams card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly-teams at https://carlyassistant.com/team/mcp. It signs in with OAuth.
Sign in with the Carly account that belongs to the organization.
2. Once it's added, the Carly Teams tools show up in the chat, including list_phone_lines. If they don't, turn Carly Teams on for the chat or start a new chat.
3. To check it worked, call list_phone_lines: it returns the teams and phone lines the account can reach. A team with no phone line yet can get one with find_numbers (optionally by area code) and get_number, which may return a checkout link to finish.
4. Something to try first: "Review our missed calls and voicemail and help me reply to customers." Carly Teams also reads and answers business texts, has the team's agent make calls, and edits the voice and text agents. Texts and calls go out at once from the agent's number and can't be taken back. Team permissions apply.
## Email, calendars and workflows
Email, calendars, files, booking pages and workflows are the regular Carly connector, added separately. It's listed in ChatGPT's plugin directory (https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54) and Claude's connector directory (https://claude.ai/directory/carly), and connects anywhere else at https://carlyassistant.com/mcp/. Its setup is https://carlyassistant.com/mcp.txt.Want Carly answering your phones?
