Quick Answer
After testing the leading platforms with real SaaS founders, the best email marketing tools for SaaS startups are Brevo for budget-conscious teams (free tier up to 2,000 contacts, 300 emails per day), MailerLite for simplicity, ActiveCampaign for advanced automation, and HubSpot for all-in-one CRM plus email. Most early-stage startups only need one or two of these to start.
If you’re searching for email marketing tools SaaS, you’ve probably noticed there are dozens of options. Every vendor claims to be the best, and the pricing models are all different — some charge by contacts, others by emails sent, and a few by features.
Here’s the truth I’ve learned from working with SaaS founders: Most startups pick the wrong tool first. They either go with whatever everyone else uses or choose an enterprise platform they don’t need yet.
I put together this guide to save you that mistake. These are the tools that actual SaaS teams rely on. No fluff. No paid promotions. Just what works based on real testing and founder feedback.
What to Look for in Email Marketing Tools for SaaS
Before we dive into the tools, let me share what actually matters for SaaS startups. After analyzing dozens of tools and talking to founders, these five factors make the biggest difference:
- Deliverability above everything else – The most beautiful email means nothing if it lands in spam. Top platforms maintain inbox placement rates above 90 percent.
- Automation that saves time – Basic autoresponders are table stakes. Advanced platforms offer conditional logic and behavioral triggers.
- Segmentation granularity – Generic email blasts convert poorly. Segmented campaigns convert significantly better.
- Pricing transparency – Many platforms advertise low monthly prices but charge separately for email sends, automation, and A/B testing. Calculate total cost before committing.
- Integration with your stack – Does it connect to your CRM, payment processor, and analytics tools? If not, keep looking.
The founders who succeed with email marketing tools for SaaS don’t buy everything at once. They pick one tool, learn it inside out, and add more as they grow.

Brevo – Best for Tight Budgets
Brevo is the tool I recommend most to bootstrapped SaaS founders. Here’s why: you get a free plan up to 2,000 contacts with 300 emails per day. That’s enough to run basic automations for months without paying a cent.
What sets Brevo apart is the pricing model. Most tools charge by contacts, which gets expensive fast. Brevo charges by emails sent. If you have a large contact list but don’t email them daily, this saves you money.
The platform supports email, SMS, WhatsApp, and web push notifications from a single workflow. The visual automation builder is intuitive enough for non-technical founders.
Who should use it: Bootstrapped SaaS startups that need professional email marketing without breaking the bank.
Cost: Free plan available. Paid plans start at $9 per month for 5,000 emails.
MailerLite – Best for Simplicity
MailerLite proves that simple doesn’t mean weak. The interface is clean and intuitive, making it easy to set up automations without technical help. The free tier supports up to 1,000 subscribers and 12,000 emails per month — generous compared to most competitors.
The drag-and-drop email builder is straightforward, and the platform includes landing page creation at no extra cost. You can capture leads without paying for separate tools.
Who should use it: Early-stage startups that want something simpler than Mailchimp but more affordable than HubSpot.
Cost: Free plan available. Paid plans start at $10 per month.
ActiveCampaign – Best for Advanced Automation
ActiveCampaign shines when you need sophisticated email sequences. The visual builder lets you create branching logic, conditional content, and multi-step workflows that adapt to user behavior in real time.
What sets ActiveCampaign apart is the lead scoring. You can assign points based on email opens, page visits, and form submissions. When a lead hits a certain score, the system can notify your sales team or move them to a different nurture track.
Who should use it: Product-led SaaS startups with complex user journeys and multiple audience segments.
Cost: No free tier. Paid plans start at $15 per month for 1,000 contacts.
HubSpot – Best All-in-One with CRM
HubSpot is the 800-pound gorilla for a reason. If you need email marketing, CRM, and sales tools in one place, it’s hard to beat. The free CRM is genuinely useful, and the email marketing features integrate seamlessly with it.
The platform tracks every interaction: email opens, link clicks, form submissions, and page visits. When a lead shows interest, you can trigger automated follow-ups or notify your sales team.
Who should use it: SaaS startups that already have product-market fit and need a unified system for sales and marketing.
Cost: Free plan available. Paid Marketing Hub starts at $15 per month for basic features.
How to Choose the Right Tool for Your Stage
Here’s what I tell founders who ask me which email marketing tool for SaaS to pick:
Just getting started (0-500 contacts): Start with Brevo or MailerLite. Both have generous free tiers, simple interfaces, and won’t lock you into long contracts.
Product-market fit (500-5,000 contacts): Move to ActiveCampaign or Kit. You need better segmentation and automation at this stage.
Scaling (5,000+ contacts): Consider HubSpot if you need CRM integration, or stick with ActiveCampaign if automation is your priority.
Webinar-driven SaaS: GetResponse. Having webinar hosting and email automation in one tool simplifies everything.
Event-driven SaaS: Constant Contact. The event management features are best in class.
High-volume senders: Moosend or Brevo. Both offer competitive pricing for large email volumes.
Common Mistakes SaaS Founders Make
Choosing the wrong pricing model. Some tools charge by contacts, others by emails sent. Know which model fits your business.
Starting with enterprise tools too early. You don’t need HubSpot Professional at nearly $900 per month when you have 500 contacts. Start small, scale later.
Ignoring deliverability. It doesn’t matter how good your emails are if they land in spam. Choose platforms with strong sender reputations and authenticate your domains.
Building overly complex workflows. Most SaaS teams only need three to five automation sequences: welcome, trial activation, upgrade, churn prevention, and re-engagement. Start there.
Not cleaning your lists. Sending to inactive users hurts your sender reputation. Remove unengaged subscribers regularly.
Frequently Asked Questions
What is the best email marketing tool for a new SaaS startup?
For early-stage SaaS startups with under 500 contacts, Brevo or MailerLite are the best choices. Both have generous free tiers, simple setup, and won’t lock you into long contracts.
Do I need email marketing if I have marketing automation?
Yes and no. Marketing automation platforms usually include email marketing as a core feature. If you already use ActiveCampaign or HubSpot for automation, you don’t need a separate email tool.
What’s the cheapest email marketing tool for SaaS startups?
Brevo’s free tier is the most generous free option. For paid plans, Moosend starts at $9 per month with unlimited email sends.
Can I switch email marketing tools later?
Yes. Most tools offer data export and import features. Many SaaS startups start with Mailchimp or Brevo and migrate to ActiveCampaign or HubSpot as their needs grow.
Which tool has the best deliverability?
ActiveCampaign, Brevo, and Mailgun consistently rank highest for deliverability. But deliverability depends more on your sending practices than the platform.
What’s the difference between email marketing and marketing automation?
Email marketing tools focus on sending campaigns and basic sequences. Marketing automation platforms offer advanced behavioral triggers, lead scoring, CRM integration, and multi-channel workflows.
Wrapping This Up
Email marketing tools for SaaS won’t fix a broken product or replace a weak marketing strategy. But if you’re already doing things that work, the right tool helps you do them faster, at scale, and with less manual work.
Start small. Use what you buy. Ignore the hype. That’s what actually works.
