Key takeaways:
- Digital engagement software covers two different purchases: outbound sales engagement, where you message buyers who haven’t contacted you, and customer engagement platforms for support and lifecycle marketing. Decide which one you need before comparing vendors.
- Seat prices hide the real bill on the customer side. Intercom adds $0.99 per resolved Fin outcome, Zendesk charges $1.50 to $2.00 per automated resolution past a small allowance, and Twilio bills $0.0083 per US text segment before carrier fees.
- Three of the 15 publish no price at all: Braze, MoEngage and Sprinklr, and MoEngage adds a one-year minimum.
- Reply.io, entry #1, is our own product and an outbound tool rather than a help desk. It runs email, LinkedIn, calls, SMS and WhatsApp steps in one branching sequence from $89 a seat each month on annual billing. You can trial it for 14 days, but there’s no free plan.
Customer experience is slipping. Forrester’s Global CX Index 2025 gathered more than 275,000 customers’ ratings of 469 brands in 13 countries and found that 21% of brands fell back while only 6% improved. In the US, a quarter of brands declined for the second year running.
Digital engagement software is a common response. The trouble is that the phrase covers two products that rarely overlap, and many rankings for it mix help desks, marketing platforms and cold outreach tools on a single scale.
We split this list into those two groups instead, and read every price on the vendor’s own pages on October 10, 2026.
What Is Digital Engagement Software?
Digital engagement software is any system a company uses to reach people, and answer them, across digital channels: email, live chat, messaging apps such as WhatsApp and SMS, in-app messages, social networks and LinkedIn. Salesforce’s own definition calls it “a suite of tools that helps businesses connect with customers through digital channels, such as chat, SMS, WhatsApp, email, and more.”
What that definition leaves out is the direction of the conversation. In inbound engagement, the customer starts it by opening a chat, emailing support or tapping a push notification. Outbound engagement runs the other way: a seller contacts someone who has never heard of the company, by email, LinkedIn message or phone.
Both get sold under the same label. A chat widget, a help center or the website engagement tools that greet visitors belong to the inbound side, while a cold sequence is purely outbound.
Outbound or Customer Engagement? Choose the Group First
Once the split is spelled out, the choice usually comes down to one question: who sends the first message?
Choose Outbound Sales Engagement When You Start the Conversation
Outbound tools suit sales teams that need meetings with people who haven’t raised a hand. You load a list and build a sequence across email, LinkedIn and phone, and the software sends each step on schedule until someone replies.
The metrics are reply rate, positive replies and meetings booked. If those are the numbers you report on, entries #1 to #5 are your shortlist.
Choose a Customer Engagement Platform When the Customer Starts It
Customer engagement platforms serve buyers with a support question, users who need onboarding and shoppers who abandoned a cart. Support desks such as Intercom and Zendesk route conversations to agents and AI, while lifecycle platforms such as Braze and Customer.io send messages triggered by what a user does.
Here the metrics are resolution time, satisfaction scores, activation and retention, which is the job of entries #6 to #15.
Signs You’re Shopping in the Wrong Group
Mapping your customer touchpoints first makes these warning signs easy to spot in a demo, because each touchpoint belongs to one side or the other.
- You need a ticket queue, SLAs and a help center, and the vendor keeps showing you email sequences.
- You need cold outreach, and the pricing is per support agent or per resolved conversation.
- The tool can only message contacts who opted in or who use your app, and your targets have never heard of you.
- Your legal team asks about consent for marketing texts while you’re evaluating a sales tool, or the reverse.
If two or more of these apply, switch groups before you spend time on a pilot.
How We Chose These Digital Engagement Tools
We started from the pages ranking for “digital engagement software”, then applied three tests.
Each tool had to reach people on at least two digital channels from one product (Instantly, an email specialist, is the one exception), fit cleanly into one group, and have a pricing model we could read, even when the answer was “quote only.”
Braze, MoEngage and Sprinklr made the list without a public price, because leaving the enterprise platforms out would make the customer engagement group look cheaper than it is.
We left out CRMs, standalone chatbots and social schedulers, and kept one entry per company: Zendesk now sells Forethought’s AI agents, so Forethought sits inside Zendesk’s entry.
The 15 Best Digital Engagement Software Compared
The “Built for” column tells you which group a tool belongs to before you read its entry, and like “Best for” and “Main limitation” it’s our own judgment. Each price is the cheapest one the vendor publishes, with the billing basis wherever the vendor states one.
| Tool | Built for | Best for | Key channels | Main limitation | Pricing (from) |
| Reply.io | Outbound sales | Multichannel prospecting sequences | Email, LinkedIn, calls, SMS, WhatsApp | LinkedIn is $69/month per account on Email Volume | $49/month annual (1,000 active contacts) |
| Woodpecker | Outbound sales | Usage-priced cold email | Email, LinkedIn add-on | No calls, SMS or WhatsApp | $24/month annual (500 prospects) |
| Instantly | Outbound sales | High-volume cold email | Full inbox only from Hypergrowth | $37.60/month annual | |
| Lemlist | Outbound sales | Email-first teams adding LinkedIn | Email, LinkedIn, SMS, calls | LinkedIn and SMS need Multichannel | $55/month annual |
| La Growth Machine | Outbound sales | LinkedIn-led outreach | LinkedIn, email, calls, X | Calls from Pro, X from Ultimate | $60/identity/month annual |
| Intercom | Support | AI-first customer service | Chat, email, in-app, phone | Two meters: seats plus outcomes | $19/seat annual ($29 monthly) + $0.99/outcome |
| Zendesk | Support | Omnichannel help desks | Email, messaging, chat, voice | Entry plan is email only | $19/agent annual |
| Salesforce Service Cloud | Support | Teams already on Salesforce | Chat, messaging, email | Messaging channels sold on top | $25/user/month (Starter Suite) |
| Freshdesk Omni | Support | Budget omnichannel support | Chat, messaging, email | 500 AI sessions once, then paid | $29/agent annual |
| Sprinklr | Support | Global service and social care | 30+ digital and voice channels | No public price or trial | Quote only |
| Brevo | Marketing | Small-business email and SMS | Email, SMS, WhatsApp, push | WhatsApp from Professional | Free; $8.08/month annual |
| Customer.io | Marketing | Product-led lifecycle messaging | Email, push, in-app, WhatsApp | SMS sends priced custom | $100/month, monthly billing |
| Braze | Marketing | Consumer apps at scale | Push, in-app, email, SMS, WhatsApp | No public price | Quote only |
| MoEngage | Marketing | Mobile-first consumer brands | Push, email, SMS, WhatsApp, in-app | One-year minimum | Quote only |
| Twilio | Developers | Building your own messaging | SMS, WhatsApp, voice, email | You build the interface | $0.0083/SMS segment + fees |
Reply.io appears in row one because it’s the product we make and sell, which is the only reason it skips the ordering rule below. The outbound tools follow in order of lowest published price on annual billing. The customer engagement group runs by job (support desks, then the enterprise suite, then lifecycle marketing, then developer infrastructure), using the same price rule inside each job with quote-only tools last.
Group 1: Outbound Sales Engagement Software
The five outbound tools here start conversations with prospects who don’t know you yet, and none of them is a support desk.
1. Reply.io
Best for: Sales teams prospecting across channels
Overview: Reply.io is outbound sales engagement software. It has no help desk, ticketing, knowledge base or website chat widget, so if you’re buying for support or lifecycle marketing, go straight to the customer engagement group at #6.
We built it for the first conversation with a buyer. One sequence can mix email, LinkedIn, calls, SMS and WhatsApp, and Yes/No conditions choose the next channel from what the prospect did. WhatsApp steps run as semi-automated tasks, so a rep sends each one.
LinkedIn steps send connection requests, messages and voice messages through our LinkedIn automation, so a prospect who ignores email still hears from you. Email and LinkedIn replies then arrive in one inbox, sorted by AI into categories such as Interested or Not now, while SMS keeps its own inbox.
Kept, a COBRA and offboarding company, shows why the mix matters. Its cold email drew replies from under 1% of prospects, and email stopped being its main channel, while LinkedIn responses ran at 7-8% and reached roughly 20% at best. With a team of two, Kept went from about 20 customers in total to winning 20 to 40 new ones a month.
Key features:
- Yes/No branches on opens, replies and other behavior that can route a prospect to any channel
- A Power Dialer that works a call list from the task and logs outcomes
- SMS from rented numbers in the same sequence (US texting needs A2P 10DLC registration)
- WhatsApp and other manual steps queued in Task Flow and worked from our Chrome extension
- A Zapier step that adds any other channel to a sequence
- A Channel Efficiency report that counts meetings booked per channel
Pricing: on Email Volume you pay for active contacts: 1,000 of them run $49 a month if you commit for a year, or $59 on monthly terms. LinkedIn sits on top of that plan at $69 monthly for each connected profile, and Calls & SMS is a $29 monthly add-on whose numbers, minutes and texts come out of a prepaid wallet. The seat-based Multichannel plan bundles one LinkedIn profile and Calls & SMS for every user at $89 a seat on yearly billing, or $99 paid month by month. There’s no free plan; new accounts get 14 days to test it, and no card is asked for at signup.
Pros: every outbound channel in one branching sequence, email and LinkedIn replies in one inbox, a dialer inside the sequence, meetings reported by channel, prices published for monthly and annual terms
Cons: LinkedIn costs extra on Email Volume ($69 monthly per profile) and calling runs on prepaid wallet credit, and we’re not a support desk, marketing-automation platform or CRM, so you’ll keep those systems alongside us
How to start using it:
- Register through the link below, then connect a sending mailbox and the LinkedIn profile you prospect from.
- Build four steps: an email, a LinkedIn connection request, a Yes/No condition on opens, and a call task for openers.
- Turn on Cloud Calls, rent a number and fund the wallet before the first call comes due.
- Add a WhatsApp task for markets where your buyers use it.
- After two weeks, open Channel Efficiency and shift effort toward the channel booking the most meetings.
Why it leads the outbound group: in Reply.io the channel is a decision the sequence makes for each prospect, rather than a separate tool a rep switches to. When one channel stops paying off, as cold email did for Kept, you change the sequence rather than the software.
Final verdict: pick Reply.io if your team creates conversations with buyers across email, LinkedIn and phone and wants one sequence and one inbox for them. If your conversations start with a customer asking for help, you’ll get more from Intercom or Zendesk in the second group.
