Choosing marketing automation software comes down to five decisions: which CRM the tool must share data with, whether your business sells online or through a sales team, which workflows you will really build in the first six months, how the vendor prices contacts and seats as you grow, and who will run the system day to day. Start with your CRM and your business model. Those two answers rule out most of the market before you see a demo.
Every platform in this category can send a welcome series. The differences that matter are in data, lead management, pricing jumps between tiers and how much skill the tool demands from your team.
Start with your CRM and sales process
Marketing automation is only as useful as the data it shares with sales. If your sales team works in a CRM, the automation tool has to read and write to it reliably: new leads, lifecycle stages, scores, deal stages and activity history.
- Already on HubSpot CRM: HubSpot Marketing Hub is the natural fit, because marketing and sales share one database with no sync to maintain.
- On Salesforce or Microsoft Dynamics: look at Adobe Marketo Engage for larger teams, or a tool with a strong native Salesforce sync for smaller ones.
- No CRM yet: consider a platform with a built-in CRM. HubSpot’s CRM is free, ActiveCampaign includes a basic CRM with enhanced pipelines sold as an add-on, and Brevo includes a CRM too.
Ask each vendor to show the sync live: create a lead from a form, change its score, and watch it appear in the CRM with the right owner. Sync errors are the most common reason automation projects stall.
Match the platform to your business model
The same features mean different things for different businesses, so be clear about how you make money.
B2B and service businesses
You need lead scoring, form and page tracking, long nurture sequences and a clean handoff when a lead is ready for sales. Look for scoring on both fit (job title, company size) and behavior (pages viewed, emails clicked), plus alerts to the assigned rep. HubSpot, ActiveCampaign and Marketo handle this well. ActiveCampaign’s lead scoring comes through its Pipelines add-on, so check that it is in your quote.
Ecommerce brands
You need flows triggered by orders, carts, product views and inactivity, with product data pulled into each message. Klaviyo is built for this. It syncs order and browsing data from Shopify and other store platforms and runs abandoned cart, browse abandonment and win-back flows out of the box. A B2B-focused tool can send these emails too, but usually with less store data behind them.
Small businesses and nonprofits on a tight budget
You need email plus a few dependable automations and maybe SMS. Brevo combines email, SMS and WhatsApp with paid plans from $9 a month, and Mailchimp is an easy starting point, though its free plan excludes automation flows.
List the workflows you will actually build
Overbuying is the most common mistake in this category. Write down the five workflows that would make the biggest difference in the next six months, then check each tool against that list, not its full feature page. A typical starting set:
- Welcome series for new subscribers or customers.
- Lead magnet or demo request follow-up, with a sales alert.
- Lead scoring that moves contacts between lifecycle stages.
- Re-engagement for contacts who have gone quiet.
- Post-purchase or onboarding sequence for new customers.
Then check which plan includes each piece. In HubSpot, full workflow automation sits in Professional, not Starter. In ActiveCampaign, landing pages start on Plus, while predictive sending, attribution and A/B testing of whole automations start on Pro. In Mailchimp, multi-step flows effectively need Standard or higher.
Get data, consent and channels right
Automation multiplies whatever is in your database, good or bad. Before you build, decide which fields drive segmentation and scoring, clean duplicates and agree on lifecycle stage definitions with sales.
Consent rules apply to every channel you automate:
- Email: CAN-SPAM in the US, GDPR in the EU and UK, and CASL in Canada set rules for consent, identification and unsubscribes. Gmail and Yahoo also require bulk senders to authenticate their domain with SPF, DKIM and DMARC.
- SMS: in the US, the TCPA requires prior express written consent for marketing texts, and carriers require business senders on standard local numbers to register through A2P 10DLC.
- WhatsApp: business messaging requires opt-in and approved message templates for messages a business starts.
Choose a tool that stores consent by channel, shows when and how each contact opted in, and makes it easy to honor opt-outs everywhere at once.
Decide what reporting and attribution you need
Marketing automation is supposed to prove which campaigns turn contacts into customers. Decide early what you need to report, because attribution features often sit on higher tiers.
- Campaign reporting: opens, clicks, conversions and revenue per email or flow. Every platform covers this.
- Workflow reporting: how many contacts enter, exit and convert at each step, so you can fix weak points.
- Attribution: which channels and touches led to a deal or sale. ActiveCampaign includes attribution from its Pro plan, and HubSpot offers multi-touch attribution as part of its advanced marketing reporting.
- Revenue reporting tied to the CRM: pipeline and closed revenue by campaign. This needs a reliable CRM sync, which is why the CRM decision comes first.
Be realistic about what your team will read. A small business usually needs a monthly view of leads, sales and the top flows. A B2B team with a sales development function needs pipeline by source and lead stage conversion rates. Ask each vendor to build the one report your leadership already asks for, using trial data, before you sign.
If you sell online, check whether revenue numbers match your store platform. Klaviyo pulls order data directly from Shopify and other platforms, which makes its revenue reporting easier to trust for ecommerce teams than numbers stitched together by hand.
Model total cost a year out
Most platforms price by contacts or active profiles, and some add seats and one-time fees. Entry prices are low, but the jumps between tiers are where budgets break.
- HubSpot Marketing Hub: free tier, Starter at $9 per seat per month on annual billing, and Professional at $800 per month on annual billing with three seats included, plus a one-time $3,000 onboarding fee. Enterprise starts at $3,600 a month.
- ActiveCampaign: at 1,000 contacts, Starter costs $15 a month, Plus $49, Pro $79 and Enterprise $145. Pro includes 3 users and Enterprise 5.
- Brevo: a free plan, Starter at $9 a month, Standard at $18 and Professional from $499.
- Klaviyo: a free plan for 250 active profiles, then paid email plans from $20 a month.
- Adobe Marketo Engage: sold in packages by quote only.
Estimate your contact count in 12 months and price that tier. Add extra seats, SMS credits and any onboarding or implementation partner fees. For enterprise platforms, include the cost of a trained admin, because tools like Marketo need one to run well.
Plan implementation and test with a real workflow
Implementation takes longer than most teams expect. A small business can set up email, forms and a few automations in a few weeks. A B2B team moving lead scoring and CRM sync to a new platform should plan for a few months, especially with a migration from an older tool.
During the trial, rebuild one workflow you actually need, end to end. ActiveCampaign offers a 14-day trial with no credit card, and HubSpot and Brevo let you start on free plans. Time how long it takes, check the reporting on it, and ask the person who will maintain it whether they could fix it alone.
- Import a clean sample of real contacts, with consent fields.
- Connect your website forms and your CRM.
- Build one complete workflow with a branch and a sales alert.
- Send real test messages by email and, if you use it, SMS.
- Review the workflow report and the contact timeline.

Frequently asked questions
Do you need marketing automation if you already have an email tool?
Not always. If you send newsletters and a welcome series, your email tool may be enough. You need marketing automation when you want lead scoring, behavior-based branching, sales alerts or one view of a contact across email, forms, SMS and your CRM. That is the point where a dedicated platform pays for its higher cost.
How long does it take to see results from marketing automation?
Simple workflows such as a welcome series or demo follow-up can show results within weeks of launch. Lead scoring and nurture programs take longer, often a few months, because you need enough contacts moving through them to tune scores and content. Set a baseline before launch so you can measure the change.
Should your team hire an admin for marketing automation?
It depends on the platform. Small businesses on ActiveCampaign, Brevo or HubSpot Starter can usually manage with a marketer who learns the tool. Enterprise platforms such as Adobe Marketo Engage need trained admins or a partner. Budget for that person or partner as part of the platform’s real cost.
Can you switch marketing automation platforms without losing data?
You can move contacts, fields, consent records and most activity data, usually through CSV exports or a CRM sync. Workflows, scoring rules, templates and reports almost never transfer, so you will rebuild them. Document your current workflows first, and run the old and new systems side by side briefly to catch gaps.
