Best Email Sequence Tools for B2B Trial Conversion

For a B2B company whose free trial or pilot is followed up by a salesperson, the best sequence tool is Encharge Premium, at $159 a month for up to 2,000 subscribers. It keeps the trial emails and the sales handoff in one flow: Stripe triggers for trial started, ends, converted and expired, plus steps that create a HubSpot deal, change its stage, create a HubSpot task and post to Slack, with a Salesforce lead step as well. The page assumes 20 to 500 trials a month, one to six reps, a marketer who writes the trial emails, and an engineer who can send a few product events. If your reps already work in HubSpot Sales Hub or Pipedrive, the comparison below tells you when another choice is better. Each dollar figure was taken from the linked vendor page on 7 October 2026.

"Trial conversion with sales" is a different job from the self-serve case covered in trial conversion sequences. Two parties write to the same person, the product and a rep, and the sequence's main work is deciding who speaks when. Rep-written sequences are covered on the SaaS sales follow-up page; this one is about the automated side and the point where it hands over.

Which tool for which trial setup

Who speaks when in a sales-assisted trial

Four systems can email a trial user: your marketing tool, a rep's own mailbox or CRM sequence, your billing tool, and the product itself. Write the split down before building:

Stripe is the one that catches teams out. Its customer emails page describes a setting that sends a reminder email seven days before a free trial ends, with a link to a page where the customer can add a payment method. Its webhook documentation says customer.subscription.trial_will_end is sent three days before the trial ends, and also fires for trials shorter than three days. If your own sequence has a "seven days left" email and Stripe's reminder is on, the buyer gets two on the same day.

The signal that moves an account to a rep

Product-qualified means that the product, not a form, tells you the account is worth a person's time. The signals are yours to choose, and the way to choose them is to list the last 15 to 20 accounts that bought and note which two or three events they shared in their first week. The table lists the kinds of event teams use. Thresholds are placeholders for you to set.

The seven tools, ranked for sales-assisted B2B trials

1. Encharge Premium: trial triggers and CRM steps in one flow

Encharge's Stripe triggers page lists "trial started", "trial ends" (a set number of days before, at, or after the end), "trial converted" and "trial expired". Its warning is the useful part: "trial ends" starts a flow whatever the customer's paying status, so it recommends a Check Condition step straight after the trigger. The flow step list has HubSpot triggers for deal stage match and meeting booked in HubSpot, and HubSpot actions to create a deal, change a deal stage and create a task, plus a Salesforce field-match trigger, a create-lead step, Send Slack Notification and End Flow. A "meeting booked in HubSpot" trigger is how a rep's booking stops the automated trial emails.

The pricing page shows Premium at $159 a month (or $129 billed yearly) for up to 2,000 subscribers, $269 at 5,000 and $399 at 10,000, with the HubSpot and Salesforce integrations, transactional email, API events with event-based segmentation and custom objects. Growth at $99 lists Stripe and Chargebee integrations and behaviour-based emails but marks event-based segmentation as unavailable. Neither tier caps the number of flows or the teammates who can edit them. Premium allows 12 times the subscriber limit in monthly sends, with overage at $100 per 100,000 emails.

Choose it if your trial lives in Stripe and your reps live in HubSpot. Skip it if your CRM is Pipedrive or Salesforce only: the step list shows a Salesforce lead step but no Pipedrive step, and I did not read how far the Salesforce integration goes.

2. Userlist: when the unit of qualification is the company

One of the examples on Userlist's onboarding page splits trial users by volume: high-volume users take a manual onboarding path and low-volume users get a regular self-serve email. That is the PQL branch above, presented as a standard pattern. The node list has Send Internal Note, Send Webhook, Wait Until, Condition and Exit, and the integrations list on the homepage names Salesforce, HubSpot, Pipedrive, Close, Attio and Intercom; how deep each integration goes is not stated there, so confirm that it writes what your reps need.

Userlist's pricing reads $149 a month at up to 10,000 users for Basic, $349 for Professional, with five and ten team seats respectively. A conversion goal, the node that measures trial-to-paid inside the workflow, is a Professional feature. The 14-day trial needs a card.

Choose it if trials are teams and a rep wants "company X has three active users" rather than three separate contacts. Skip it if you need sequences sent from each rep's own mailbox, since I found no mention of that in the pages I read.

3. HubSpot Marketing Hub with Sales Hub: the single-record option

The two products' Marketing Hub and Sales Hub pricing pages together give the picture. Marketing Hub lists Starter at $7 per seat with up to ten automated actions, Professional at $800 a month with 2,000 marketing contacts and three core seats, and Enterprise at $3,600 with 10,000 contacts and five. Sales Hub lists free tools for up to two users, Starter from $7 per seat, Professional from $90 per seat plus a required one-time $1,500 onboarding fee, and Enterprise from $150 per seat plus $3,500.

The relevant limit is documented in HubSpot's workflow actions guide: automatically enrolling contacts in a sequence is available on Sales Hub and Service Hub Enterprise only, and rotating a record to an owner needs Sales Hub or Service Hub Professional or Enterprise. Create task and internal email notification have no plan listed. So on Professional a product signal can create a task and notify the owner, and the rep writes the first email.

Choose it if sales and marketing already share HubSpot records. Skip it if you are starting fresh and trial volume is small, because the stack is the most expensive in the cost table.

4. ActiveCampaign: CRM and automation under one login

ActiveCampaign's pricing page lists Plus at $49 a month at 1,000 contacts, $95 at 2,500, $145 at 5,000 and $189 at 10,000, billed annually; Pro is $79, $149, $205 and $375 at the same sizes. Starter caps automations at five actions, Plus lists unlimited actions, and users run one, one, three and five from Starter to Enterprise. Deal records, account records and lead scoring are listed in a Pipelines add-on, and win probability and automated 1:1 email in a Sales Engagement add-on. I did not find a price for either on the page text, so a total for a team that wants deals is not possible from the page.

Choose it if one marketer owns the trial emails and a small sales team wants deals in the same account. Skip it if you have more than five users, since the tiers on the page stop there.

5. Customer.io: the best event engine, CRM sold separately

Customer.io's exit conditions let a trial email stop when a person meets any condition you add, such as an event, an attribute or a segment, and its trigger documentation recommends passing a timestamp attribute such as trial_start_date and using it in a Wait until block at the start of an automation. That is a trial-date mechanism that survives extensions if your app updates the attribute. The pricing page lists Essentials at $100 a month for 5,000 profiles (1 million emails), $145 at 10,000, unlimited webhooks, and the native Salesforce integration under Premium, which starts at $1,000 a month billed yearly. On Essentials, your CRM link is a webhook that you build.

Choose it if an engineer owns the trial data and you pair it with a CRM. Skip it if a marketer must wire the CRM alone.

6. Pipedrive: the CRM that sequences deals

Pipedrive's pricing page lists per seat per month, billed annually: Lite $14, Growth $39, Premium $59 and Ultimate $79. Growth is described as automating emails and follow-ups, and sequences of personalized emails and follow-ups to nurture deals are listed under its automations. It names Zapier, Zoom and Lemlist among its integrations, and offers a 14-day trial with no card. The pages I read do not describe a way to receive trial events directly, so product signals would travel through Zapier or a custom integration. Choose it if one or two reps need a pipeline first and email second. Skip it if the sequences must react to what the trial user does in the product.

7. Salesforce Account Engagement: when Salesforce is already the system of record

Salesforce's Account Engagement pricing page lists Growth+ at $1,250 a month per organisation billed annually, with 10,000 contacts, 50 automation rules and 25,000 API calls a day; Plus+ at $2,750 with 100 automation rules; Advanced+ at $4,400; and Premium+ at $15,000 with 75,000 contacts. Choose it if your company already runs Salesforce and the trial volume justifies four figures. Skip it if you are under a few thousand trials a year, since every cheaper option above does the job.

Three sequences for the trial, the extension and the end

Sequence A: days 0 to 14 with a signal branch

What to build: an entry trigger on trial start, a delay per step, an event-based exit for the signal, a second exit for a booked meeting, and a step that creates a CRM task. In Encharge Premium that is the Stripe trial started trigger, Wait, Check Condition, Create Task in HubSpot, Send Slack Notification and a "meeting booked in HubSpot" exit. In HubSpot Professional it is a workflow with a delay, a create-task action and an internal notification; the rep sends the email manually because enrolment is Enterprise only. In Customer.io it is an event-triggered automation, exit conditions on the signal event and a webhook to your CRM. In Userlist it is a workflow with Wait Until, Condition and Send Internal Note.

Sequence B: the extension request

1. Trigger: the user clicks "I need more time" in the product, replies to a trial email, or a rep decides to extend. Send the first as an event; the other two arrive as a CRM field change.
2. Within the hour: a short email from the rep naming the new end date and asking one question about what the extra days are for. Without the question the extension is a free week and nothing else.
3. Update the stored end date. Every end-of-trial email reads this one field. In Customer.io the Wait until block reads the timestamp. Encharge's trigger counts days before, at or after the trial end, and its page does not say whether an extended end date moves flows already queued, so extend the trial in Stripe too and run a test trial before a customer needs it.
4. Suppress the old countdown. Anyone mid-way through the end-of-trial sequence is exited and restarted against the new date.
5. One extension per account. Set a property when it is used so that a second request goes to the rep, not the automation.

Sequence C: the end of the trial

The two Stripe triggers that matter are "trial converted" and "trial expired" in Encharge, which split the table's last row from the rest without any code. Outside Stripe, send the same two events from your app.

What a stack costs for 1, 3 and 6 reps

The scenarios are my assumptions: one rep with about 2,000 contacts in the marketing tool, three reps with about 5,000, and six reps with about 10,000. Prices are US dollars a month from the pages linked above, excluding tax and one-time fees, and each stack pairs the marketing tool with the CRM that its own page implies. Where a vendor's tiers stop short of the scenario, the cell says so.

The HubSpot Sales Hub Starter figure is the "starts at $7" price; the page also shows $20 per seat under a second billing option, so the three- and six-rep Encharge cells would be $329 (269 + 60) and $519 (399 + 120) at that price. Whether Encharge's HubSpot integration works at Starter or only on higher Sales Hub tiers is not stated on its pricing page, which is why the Encharge row should be tested in its trial before you commit.

Reading the table: at one rep the cheapest stack I can price in full is Customer.io plus Pipedrive at $139, if you can build the webhook. At six reps the two Pipedrive stacks come within $4 of each other ($379 and $383), because six seats dominate the bill. The HubSpot-only stack at six reps, $4,140, is more than ten times either of them. That is the price of one record and one login, and it still does not include the Enterprise sales tier that the workflow-to-sequence enrolment needs.

Where sales-assisted trials go wrong

The rep gets twelve alerts for one account. A signal such as "invited a teammate" fires for each invite. Customer.io's default is that a person enters an event-triggered automation every time the event occurs, with frequency options of one time, every event or once within a time period; Userlist distinguishes one-off workflows from repeatable ones. Set the signal to fire once per account.

Two senders, one buyer. The tool keeps sending day-7 emails after the rep wrote on day 4. The stop has to be a field the CRM sets (owner assigned, deal stage) and that the tool checks before each send. If your sync runs every fifteen minutes, an email can still go out after the rep has written.

"Trial ends" fires for customers who already paid. Encharge says so itself. Put the status check right after the trigger.

Treating a form field as a product signal. Company size on a signup form is self-reported and often left blank. Use it to route, never to qualify, and ask the rep to confirm.

Sales-engineer trials and paid pilots. If every trial is set up by a sales engineer, the sequence is mostly a calendar of reminders for a human, and a CRM alone is enough. If you have thousands of trials a month and no rep can touch each, the signal branch should create a list for a small team rather than a task per account. And if your pilot is a paid proof of concept under contract, the commercial stages live in the CRM and these emails barely matter.

The self-serve counterpart is trial conversion sequences. Marketing's side before the trial starts is on the SaaS lead nurturing page.

Frequently asked questions

When should a salesperson contact a B2B trial user?

When the product shows a signal you chose in advance, not on a fixed day. Look at the accounts that bought last quarter, list the two or three things they did in their first week that non-buyers did not, and make those events the trigger for a task to the rep. Accounts that never fire the signal stay on the automated trial emails, and the rep sees them again only if they ask for help or reach the last days of the trial.

Should trial emails come from the product or from the rep?

Split them by who is expected to answer. The first-week usage emails can come from the product and a shared address that a human reads. As soon as a rep is assigned to the account, the next messages should come from the rep's own address, and the automated trial emails for that account should stop. Two senders writing to the same buyer in one week is the most common complaint in sales-assisted trials.

How do I handle a trial extension without confusing the emails?

Store the trial end date as a field and key every end-of-trial email to it, rather than to a fixed number of days after signup. When a rep extends the trial, update that one field, and the countdown emails move with it. Check what happens in your tool to emails already scheduled: Encharge's Stripe trigger fires a set number of days before, at, or after the trial end, so test an extension on a test trial before a customer gets one.

Do I need HubSpot Sales Hub to do this?

No, but you need somewhere reps see tasks and deals, and that is a CRM, whether HubSpot, Pipedrive, Salesforce or ActiveCampaign's deal records. HubSpot's own guide says a workflow action that enrols a contact in a rep's sequence is available on Sales Hub Enterprise only, so on Professional the product signal creates a task and the rep sends the first email by hand. That is often the better design anyway.

What if my trial is not billed through Stripe?

Then the trial dates and signals come from your own app. Customer.io, Userlist and Encharge Premium all accept events and properties from your code, and the flows work the same way, but you lose the ready-made trial started, ended, converted and expired triggers that Encharge builds from Stripe data. Send those four events yourself, with the trial end date as a property, and treat them as the contract between product and marketing.
