Deal won SMS fires to rep and customer

When a deal closes in HubSpot, the Sales Agent sends a congratulatory SMS to the account rep and a thank-you text to the customer — then logs both sends in the CRM deal record. The rep knows the deal closed before leaving their desk, and the customer feels valued within about a minute of signature.

What your team gets back — two angles: what you stop doing manually, and what that's worth.

With Actionist

What your agent runs for you

  • Sales
    35 min / week
    Manual SMS follow-up after each deal

    Reps copy phone numbers from the CRM, open their phone or a dashboard, type a personalised message, and send — 5 to 10 minutes per deal event, skipped when busy.

    Sales Agent
    0 min
    Agent fires deal SMS the moment the event happens

    When a deal closes or a proposal is sent, the Sales Agent sends the SMS within about a minute — personalised, logged in the CRM, and consistent whether the rep is in a meeting or on holiday.

  • Marketing
    90 min / week
    Manual export, import, and campaign launch

    The team exports a contact segment from the CRM, imports it into ClickSend, sets up the campaign name, types the message, and presses send — 45 minutes per campaign when done carefully.

    Marketing Agent
    0 min
    Agent finds the list and blasts the campaign automatically

    The Marketing Agent searches for the correct contact list by name and fires the SMS campaign in a single automated sequence — no CSV exports, no manual imports, no dashboard login required.

  • Customer Support
    60 min / week
    Inbound SMS checked manually on shift

    Someone on the support team logs into ClickSend periodically to check for incoming messages, copies contact details manually, creates a ticket, and fires a reply — replies take hours if the check is missed.

    Customer Support Agent
    0 min
    Agent converts inbound SMS to helpdesk ticket within a minute

    The New Incoming SMS trigger fires within about a minute, the agent looks up the sender, creates the helpdesk ticket, and sends an auto-reply — the customer never waits for a human to notice the text.

  • Human Resources
    25 min / week
    HR manually texts new hires on their first day

    The HR team sends individual welcome texts to new starters from a personal or shared mobile, manually updating the ClickSend contact list each time — often forgotten or delayed during busy onboarding weeks.

    Human Resources Agent
    0 min
    Agent sends welcome SMS and adds contact automatically

    When the start date arrives, the HR Agent fires the welcome SMS to the new hire's mobile and adds them to the employee-notifications ClickSend list simultaneously — zero manual effort, consistent every time.

  • Finance
    90 min / week
    Manual overdue chasing across multiple channels

    The finance team manually identifies overdue accounts, sends emails, then follows up with a phone call days later — the voice call step is often skipped under workload pressure.

    Finance Agent
    0 min
    Agent escalates overdue accounts through SMS, voice, and letter automatically

    At each overdue milestone, the Finance Agent fires the appropriate channel — SMS at 14 days, voice call at 60 days, printed letter for formal notice — without any manual involvement from the finance team.

  • Operations
    30 min / week
    Maintenance alerts sent manually before each window

    The ops team drafts a maintenance notification, logs into ClickSend, selects the contact list, and sends the broadcast — often done under time pressure and sometimes after the window has already started.

    Operations Agent
    0 min
    Agent broadcasts maintenance SMS the moment the window is scheduled

    When a maintenance window is created in the ops calendar, the Operations Agent finds the affected-customers list and fires the broadcast SMS automatically — customers know before the ops team has finished their morning coffee.

  • Legal
    45 min / week
    Manual opt-out verification and document dispatch

    The legal team manually checks ClickSend contact lists to verify opt-outs were processed, then coordinates with admin to print, sign, and post formal legal notices — each step a separate manual action.

    Legal Agent
    0 min
    Agent verifies opt-outs and dispatches legal documents automatically

    The Legal Agent verifies opt-out deletions via contact search, dispatches printed letters and faxes for formal notices, and logs everything in the compliance register — fully documented without a single manual step.

FAQs

Questions about ClickSend SMS + Actionist

How does Actionist connect to ClickSend?
Go to the Apps tab, find ClickSend SMS, and click Connect. You will be prompted to enter your ClickSend username and API key. In ClickSend, go to your Account Settings and then API Credentials to find or generate your API key. Paste both into the connection fields in Actionist and click Test connection. Actionist runs a read-only account check to confirm the handshake before any messages can be sent.
Can I use ClickSend to send SMS to contacts in the US and Canada?
Yes, but with a restriction. When sending to US or Canadian numbers, ClickSend requires you to use a dedicated number that you have purchased through ClickSend — leaving the From field blank or using an alphanumeric sender ID (like your company name) will fail. You purchase a dedicated number in the ClickSend dashboard, and your agent uses that number as the sender. For most other countries, an alphanumeric sender ID is supported and replies are possible only when using a dedicated number.
What is the difference between Send SMS, Send SMS Campaign, and Send SMS to Contact List?
Send SMS sends a single message to one phone number — ideal for transactional texts like deal confirmations, appointment reminders, or individual replies. Send SMS to Contact List sends the same message to every contact in a ClickSend list in a single action — useful for broadcasting a message to an existing group. Send SMS Campaign also targets a list but additionally creates a named campaign record in ClickSend, giving you campaign-level delivery reporting useful for marketing sends where attribution matters.
How quickly does Actionist receive an incoming SMS reply?
Actionist polls ClickSend for new incoming messages approximately every 45 seconds, so your agent typically reacts within about a minute of the message arriving on your ClickSend number. This is fast enough for most support, lead capture, and unsubscribe-processing use cases. If you need faster reaction times for customer-facing flows, design your agent response to include an immediate auto-reply so the sender knows their message was received, even while the agent processes it.
Can Actionist send physical mail like letters and postcards through ClickSend?
Yes. ClickSend's Send Letter and Send Postcard actions let your agent dispatch printed physical mail to any address globally. For letters, the agent submits a PDF via a public URL and ClickSend prints, folds, and posts it. For postcards, the PDF can be a single page (front only) or two pages (front and back). You must have a return address configured in your ClickSend dashboard before sending. This channel is particularly valuable for overdue invoice escalation, win-back campaigns for churned customers, and regulatory notices requiring written delivery.
How do I handle STOP replies and GDPR deletion requests automatically?
When a contact replies STOP to an SMS, the New Incoming SMS trigger fires within about a minute. Your agent can read the message body, detect the STOP keyword, call Search Contact by Phone to find the sender, and then call Delete Contact to remove them from all relevant lists. For GDPR deletion requests arriving via email or a form, your agent can use Search Contact by Email Address to find the contact in ClickSend and then call Delete Contact. Each deletion should be logged with a timestamp in your compliance record — the agent can write that log entry to any connected tool like Notion, Google Sheets, or your CRM.
Can I send voice calls and faxes as well as SMS through ClickSend?
Yes. ClickSend supports text-to-speech voice calls via the Send Voice action, where you provide the message text and choose the language and voice (male or female). Faxes are sent via Send Fax by providing a PDF file URL and a destination fax number in E.164 format. Both are particularly useful for compliance-heavy industries or escalation scenarios — an overdue invoice sequence, for example, might start with an SMS reminder, escalate to a voice call at 60 days, and finish with a printed letter for formal notice.
What happens if I send an SMS to a number that does not exist or is invalid?
ClickSend returns a delivery status for every SMS — if the number is invalid or unreachable, the API response includes a delivery failure status code. Your Actionist agent can read this status and take a follow-up action: log the failure in your CRM, flag the contact for manual review, trigger an email or alternative outreach, or call Update Contact to mark the phone number as undeliverable. Building this error-handling step into your agent prevents silent failures where a message appears sent but was never delivered.
