Last updated: 5 June 2025 — ⏱ 4 min read
Choosing “the best” email marketing software is less about a single champion and more about matching your budget, list size and automation needs to the right platform. Independent round-ups from EmailToolTester, Zapier and PCMag all name different winners, yet they consistently highlight a handful of platforms—including Moosend, GetResponse and Brevo—that lead on price-to-feature ratio. Below, we break down the top categories—budget, automation muscle, ease of use, and all-in-one capability—so you can pick confidently. (When you spot an internal link, it jumps to our full hands-on review.)
1 Best for Tight Budgets: Moosend
Moosend’s forever-free tier supports up to 1,000 subscribers and includes automation workflows, landing pages and 70+ templates—features most rivals hide behind paywalls. EmailToolTester calls it “the best low-cost option for small businesses.” If cost control matters, start with our Moosend review. You can test moosend for free for 30 days.
2 Best AI-Powered Automation: GetResponse
GetResponse pivoted hard into AI this year—subject-line generator, send-time optimisation and funnel suggestions all baked in. Business.com ranks it “Best for AI-Powered Automation,” noting its new website-builder and webinar tools as unique extras. If you’re keen on smart automations but still want sane pricing, dive into our GetResponse review.
3 Best for Growing Lists at Scale: Pabbly Email Marketing
Pabbly’s headline feature is unlimited subscribers on paid tiers and a flat-rate pricing model that rarely spikes as your list explodes. Reddit threads praise it as a “set-and-forget” sender once you hook in an SMTP relay. Check the details—including deliverability tests—in our Pabbly review.
4 Best All-in-One Funnel Builder: Systeme.io
Need email + landing pages + course hosting but hate duct-taping tools together? Systeme.io offers funnels, checkout and automation in a single UI. The free plan includes 2,000 contacts—plenty for side projects. TechRadar lists it as an “honourable mention” for all-in-one convenience. Our Systeme review covers the real-world pros and cons.
5 Popular Alternatives Worth Knowing
| Use-Case | Stand-out Tool | Why It Could Beat Your First Choice |
|---|---|---|
| Beginner-friendly drag-and-drop | Mailchimp | Ubiquitous integrations and a free 500-contact tier, but cost climbs fast on growth. |
| Advanced data + ecommerce | ActiveCampaign | Powerful segmentation and site tracking, ideal for multi-channel automation. |
| Cost-effective SMS + email | Brevo (Sendinblue) | Multichannel (email, SMS, WhatsApp) in one interface; strong European deliverability. |
| Agency-grade deliverability | Campaign Monitor | Highest inbox placement in PCMag’s 2025 tests but pricier at scale. |
| Simple newsletters | MailerLite | Frequently recommended in Zapier’s free-plan round-up for ease of use. |
Quick note: We haven’t published deep-dive reviews on these five yet, but they’re solid benchmarks when comparing against Moosend, GetResponse, Pabbly and Systeme.io.

7 How to Choose the “Best” Platform for You
- Set your growth horizon. A free 500-contact plan may look fine today, but if you’ll hit 10K contacts in six months, Pabbly’s flat-rate or Moosend’s low-tier plan wins on cost.
- Audit must-have integrations. Shopify shops lean toward Klaviyo; WordPress blogs often pick Mailchimp or MailerLite. Check API docs before migrating.
- Prioritise automation depth. Simple newsletters? Systeme.io or MailerLite. Complex e-commerce flows? GetResponse or ActiveCampaign.
- Test deliverability. Sign up to GlockApps or Mail-Tester and compare inbox placement on your list’s most common providers (Gmail, Outlook).
- Demand transparent pricing. Avoid platforms that force demos to reveal costs—budget creep kills ROI.
