The Price Gap That Changes Everything

I tested both platforms for two months with a boutique e-commerce client (7,500 subscribers, $200k annual revenue). The feature comparison mattered less than the spreadsheet.

Annual cost at 10k subscribers:

• Campaigner Essential: $2,148/year
• MailerLite Advanced: $600/year (with 30% annual discount)
• Difference: $1,548/year

That's $1,548 you could spend on product development, customer acquisition, or paying yourself. For a bootstrapped small business, this isn't a rounding error—it's meaningful budget.

The question isn't whether Campaigner is better. It is. The question is whether it's $1,548/year better. For most small businesses, the answer is no.

What You Lose by Choosing MailerLite

Let's be honest about MailerLite's limitations:

Automation is basic. MailerLite has trigger-based sequences (subscriber joins list → send email series). Campaigner has conditional workflow branching (if they open email A but not email B, wait 3 days then send email C unless they clicked link D).

For complex B2B lead nurturing, Campaigner wins. For straightforward welcome sequences and product launches, MailerLite is sufficient.

Multivariate testing is limited. MailerLite offers A/B testing (2 variants). Campaigner offers full multivariate testing—test 5 subject lines against 3 content blocks (15 combinations).

If you're obsessed with optimization and have enough volume to make multivariate testing meaningful (15k+ subscribers), Campaigner wins. For most small businesses, A/B testing is enough.

Template quantity is lower. Campaigner has 900+ templates. MailerLite has 100+. But here's the thing: MailerLite's templates are modern, mobile-responsive, and actually usable. Campaigner's library includes outdated designs from 2018-2019 and weirdly specific industries.

I'd rather have 100 great templates than 900 mediocre ones. For email design, MailerLite's curated selection beats Campaigner's overwhelming quantity.

What You Gain by Choosing MailerLite

MailerLite includes features Campaigner doesn't offer at all:

Unlimited landing pages. MailerLite lets you build landing pages for lead capture, product launches, and event registrations. Campaigner offers no landing page builder—you'll use Unbounce ($99/mo), Instapage ($199/mo), or Carrd ($19/year).

I built three landing pages in MailerLite for a client's lead magnet campaign. The builder is intuitive, templates are modern, and pages load fast. This feature alone saves $20-100/month compared to separate landing page tools.

Website builder. MailerLite includes a basic website builder. It's not WordPress, but it's good enough for simple one-page sites or portfolio pages. Campaigner offers nothing similar.

Generous free tier. MailerLite is free up to 1,000 subscribers (12,000 emails/month). Campaigner has a 14-day trial then starts at $179/mo. For bootstrapped startups building their list, MailerLite's free tier is valuable. Read more about free email marketing tools.

30% annual discount. Pay annually and MailerLite discounts 30% ($50/mo becomes $35/mo). Campaigner offers 10% annual discount. Over three years at 10k subscribers, this is $1,080 in additional savings.

Deliverability: The Great Equalizer

Both platforms have solid deliverability. MailerLite is strict about list hygiene—mandatory double opt-in for new subscribers, aggressive monitoring of engagement rates, no purchased lists allowed.

Campaigner uses SparkPost infrastructure with strong deliverability reputation. In our tests across five different industries:

• MailerLite inbox placement: 94%
• Campaigner inbox placement: 93%

The difference is negligible. Your sending practices (list quality, engagement, avoiding spammy content) matter far more than the platform. Both will deliver emails reliably if you follow best practices.

Automation Reality Check

I rebuilt the same automation workflow in both platforms—a 7-email welcome sequence with conditional branching based on engagement.

In Campaigner: Took 90 minutes. The workflow builder is powerful but has a learning curve. I could set advanced conditions (if they opened email 2 but didn't click any links, wait 2 days then send email 3A instead of 3B).

In MailerLite: Took 35 minutes. The automation is simpler—tag-based triggers and linear sequences. I couldn't build the same complex conditional logic, so I simplified the workflow.

The result? Both versions converted at similar rates (41% vs 43%). The complex Campaigner workflow didn't meaningfully improve outcomes. For most small business use cases, MailerLite's simpler automation is sufficient.

For email automation in SaaS businesses, neither platform is ideal. You'll use Zapier to connect Stripe and manually build workflows for trial conversion, payment failures, and churn. Sequenzy handles this natively.

The Template Paradox

Campaigner's 900 templates sound impressive until you browse them. Many are:

• Outdated design trends (2018-2020 era)
• Weirdly specific industries (veterinary clinic newsletters, auto dealership promotions)
• Not mobile-optimized
• Require significant customization

MailerLite's 100+ templates are curated and modern. Every template is mobile-responsive, follows current design trends, and looks professional out of the box. I found usable templates faster in MailerLite despite having 1/9th the quantity.

Sequenzy takes a different approach: 20 clean templates plus AI that writes the content for you. You're not scrolling through 900 templates—you're describing your email in plain English and letting AI build it.

Pricing Reality at Different List Sizes

Let's look at costs as your list grows:

Subscribers	Campaigner	MailerLite	Sequenzy
1,000	$179/mo	Free	Free
5,000	$179/mo	$30/mo	$29/mo
10,000	$179/mo	$50/mo	$49/mo
25,000	$179/mo	$100/mo	$99/mo
50,000	$399/mo	$155/mo	$149/mo

The price gap narrows as you grow, but MailerLite remains 2-3x cheaper than Campaigner at every tier. For pricing transparency, both platforms are honest about costs (unlike some competitors with hidden fees).

The SaaS Problem Neither Solves

If you're running a SaaS business, both platforms require manual Stripe integration:

With Campaigner:

• Connect Stripe via Zapier ($20-30/mo for necessary task volume)
• Build custom workflows for trial conversion, payment failures, churn
• Manually tag users by subscription status
• Create segments for MRR, plan type, billing interval
• Ongoing maintenance when Stripe changes webhook formats

With MailerLite:

• Same Zapier requirement
• Simpler automation means less flexibility for complex SaaS workflows
• Tag-based system requires manual maintenance
• No native concept of MRR, LTV, or subscription status

I spent two weeks building a Stripe → MailerLite integration for a SaaS client. It worked but felt fragile—breaking twice over six months when Stripe updated their API.

Sequenzy's Stripe integration is native. Connect your account and it automatically:

• Tags users by subscription status (trial, active, past_due, cancelled, churned)
• Tracks MRR and LTV per contact
• Triggers automations on payment events (trial ending, payment failure, churn)
• Segments customers by plan, billing interval, and trial status

For SaaS companies, this saves 15-25 hours of setup and eliminates ongoing integration maintenance. Read more about email marketing for SaaS.

Support: Where MailerLite Surprises

MailerLite offers 24/7 email support on all plans, including the free tier. Response times average 2-4 hours in my experience. Campaigner offers email support with longer response times (6-12 hours), phone support on higher tiers.

For small businesses, MailerLite's responsive support is a hidden strength. You're not paying $179/mo and still waiting 12 hours for email responses.

Sequenzy offers direct founder support via email. You're not escalated to tier 2—you talk to the people who built the product. Response times under 4 hours on business days.

The Verdict: Budget vs Features

Choose Campaigner if:

• You're an enterprise B2B marketing team with budget
• You need complex automation with multivariate testing
• You're running sophisticated conditional workflows
• You have a dedicated email marketing manager
• Advanced features justify 3.6x higher cost

Choose MailerLite if:

• You're a small business watching budget closely
• You want landing pages without separate tool subscriptions
• Simple automation meets your needs (welcome sequences, product launches)
• You're building your list and want a generous free tier
• Paying $50/mo instead of $179/mo matters for your business

Choose Sequenzy if:

• You're running a SaaS business on Stripe
• You want AI to generate email sequences for you
• You need transactional + marketing emails in one platform
• You want $49/mo pricing with all features included
• You value Stripe integration over landing pages

Sequenzy's Honest Limitations

We don't compete with MailerLite for general small business use. We don't have:

• Landing page builders
• Website builders
• E-commerce integrations (Shopify, WooCommerce)
• Product recommendation engines
• SMS capabilities

What we do have: the best Stripe integration in email marketing. If you're selling software subscriptions, we're purpose-built for your business model. If you're a small business needing landing pages and website builders, MailerLite is the better choice.
