GetResponse — Best Overall Email Marketing Platform in 2026
GetResponse earned the top spot because it consistently delivered across every category we tested. It is not the absolute best in any single area — ActiveCampaign has better automation, ConvertKit is more creator-friendly — but no other platform offers this level of completeness at this price point.
During our 90-day test, GetResponse achieved a 95.4% deliverability rate across 15 campaigns. The visual automation builder handled everything from simple welcome sequences to complex multi-branch workflows with conditional logic. What really sets it apart is the inclusion of landing pages, webinar hosting, and conversion funnels — features that competitors charge extra for or do not offer at all.
What We Liked
- + Landing pages included on all plans
- + Webinar hosting (up to 500 attendees)
- + Visual automation builder with 40+ templates
- + 24/7 live chat support on all plans
- + Conversion funnel builder included
- + AI-powered subject line generator
What Could Be Better
- - No permanent free plan (14-day trial only)
- - Email template designs feel slightly dated
- - SMS marketing requires paid add-on
- - Steeper learning curve than Mailchimp
GetResponse Pricing (February 2026)
| Plan | 1,000 contacts | 5,000 contacts | 25,000 contacts |
|---|---|---|---|
| Email Marketing | $19/mo | $54/mo | $174/mo |
| Marketing Automation | $59/mo | $95/mo | $255/mo |
| E-commerce Marketing | $119/mo | $169/mo | $359/mo |
ActiveCampaign — Best Email Automation Platform for B2B
If your primary need is building sophisticated, multi-step automation workflows with conditional branching, lead scoring, and CRM integration, ActiveCampaign is unmatched. The automation builder is the most powerful we have tested in any price range below enterprise-level tools.
During testing, we built a 12-step lead nurturing workflow with 4 conditional branches, goal tracking, and CRM deal creation — all within the visual builder. No other platform in this comparison could replicate that level of complexity without workarounds. The built-in CRM alone saves $30-50/month compared to using a separate tool like Pipedrive or HubSpot Starter.
What We Liked
- + Most powerful automation builder in its class
- + Built-in CRM with deal pipelines
- + Predictive sending and content
- + 900+ integrations
- + Site and event tracking
What Could Be Better
- - Steepest learning curve of all tested tools
- - No free plan
- - No landing page builder
- - Pricing scales aggressively with contacts
ConvertKit — Best Email Platform for Bloggers and Content Creators
ConvertKit was purpose-built for bloggers, podcasters, YouTubers, and independent creators who want to grow an audience and monetize it through email. The standout feature is unlimited subscribers on all paid plans — a pricing model that no other major platform offers.
For a creator with 10,000 subscribers, ConvertKit costs $29/month. The same list on GetResponse would cost $80/month, and on ActiveCampaign around $139/month. That cost advantage becomes massive as your list grows. The paid newsletter feature (ConvertKit Commerce) lets you charge subscribers directly, with Stripe handling payments and ConvertKit managing access — no third-party tools needed.
What We Liked
- + Unlimited subscribers on all paid plans
- + Paid newsletter monetization built-in
- + Clean, distraction-free interface
- + Tag-based subscriber management
- + Free plan for up to 1,000 subscribers
What Could Be Better
- - Landing pages are a paid add-on
- - No webinar functionality
- - Limited e-commerce features
- - Email template options are minimal
Mailchimp — Best for Getting Started With Zero Budget
Mailchimp remains the most recognizable name in email marketing, and its free plan is still one of the best ways to start sending emails without spending a dollar. For solopreneurs and very small businesses with fewer than 500 contacts, it is a solid entry point.
However, Mailchimp has become significantly more expensive on paid plans since its acquisition by Intuit. The Standard plan for 5,000 contacts now costs $75/month — more than GetResponse ($54/month) for fewer features. The automation capabilities are basic compared to GetResponse or ActiveCampaign, and the free plan limits you to 500 contacts with Mailchimp branding on every email.
What We Liked
- + Free plan available (500 contacts)
- + Familiar, beginner-friendly interface
- + Large template library
- + Strong brand recognition
What Could Be Better
- - Expensive on paid plans vs competitors
- - Basic automation only
- - Free plan has Mailchimp branding
- - Deliverability dropped in our tests (91.2%)
Also Worth Considering: Brevo, Klaviyo, and MailerLite
Brevo (formerly Sendinblue) — Best for Transactional + Marketing Emails
Brevo is the best choice if you need both transactional emails (order confirmations, password resets) and marketing emails in one platform. Their pricing is based on emails sent rather than contacts stored, which can be cheaper for businesses with large but infrequent-send lists. The free plan allows 300 emails per day with unlimited contacts.
Best for: SaaS companies, marketplaces, businesses needing transactional + marketing in one tool.
Klaviyo — Best for Shopify and E-commerce
If you run a Shopify store, Klaviyo is purpose-built for you. The Shopify integration is deeper than any competitor, with real-time product data syncing, predictive analytics for customer lifetime value, and pre-built e-commerce flows (cart abandonment, browse abandonment, post-purchase). The free plan supports up to 250 contacts.
Best for: Shopify stores, DTC brands, e-commerce businesses doing $500K+ in annual revenue.
MailerLite — Best Budget Option
MailerLite offers the lowest starting price ($10/month for 500 subscribers) with a surprisingly capable feature set. The free plan supports up to 1,000 subscribers with 12,000 monthly emails. It lacks the advanced automation of GetResponse or ActiveCampaign, but for simple newsletters and basic sequences, it gets the job done at a fraction of the cost.
Best for: Freelancers, side projects, non-profits, anyone prioritizing low cost over advanced features.
Email Marketing Pricing Comparison 2026: What You Actually Pay as You Grow
Starting prices are misleading. What matters is what you pay at 5,000, 10,000, and 25,000 subscribers — because that is where most businesses feel the cost pressure. Here is the real pricing at scale:
| Subscribers | GetResponse | ActiveCampaign | ConvertKit | Mailchimp | ||||
|---|---|---|---|---|---|---|---|---|
| 1,000 | $19 | $29 | $29 | $13 | $10 | |||
| 5,000 | $54 | $99 | $29 | $75 | $39 | $29 | $75 | $39 |
| 10,000 | $79 | $139 | $29 | $110 | $73 | |||
| 25,000 | $174 | $259 | $29 | $270 | $139 | |||
| 50,000 | $299 | $449 | $29 | $385 | $223 |
Key insight: ConvertKit's unlimited subscriber model makes it the cheapest option at scale. However, it lacks landing pages, webinars, and advanced automation. If you need those features, GetResponse offers the best value per dollar at every tier.

- ☐ Check that your existing tools (CMS, CRM, e-commerce) integrate

- ☐ Verify deliverability by sending to Gmail, Outlook, and Yahoo test accounts
5 Mistakes People Make When Choosing an Email Marketing Platform
After helping dozens of businesses migrate between platforms, these are the errors we see repeatedly:
Mistake 1: Choosing based on the free plan alone
Free plans are designed to get you locked in. By the time you outgrow them, migrating is painful. Choose based on what you will need at 5,000-10,000 subscribers, not at 500.
Mistake 2: Ignoring deliverability rates
A 3% difference in deliverability means hundreds of emails landing in spam instead of inboxes. On a 10,000-subscriber list, that is 300 people who never see your message. Always test deliverability before committing.
Mistake 3: Overbuying features you will never use
ActiveCampaign is powerful, but if you only send a weekly newsletter, you are paying for automation capabilities you will never touch. Match the tool to your actual workflow, not your aspirational one.
Mistake 4: Not calculating cost at scale
A platform that costs $19/month at 1,000 subscribers might cost $299/month at 50,000. Always project your costs 12-24 months ahead based on expected list growth.
Mistake 5: Switching platforms too often
Every migration risks losing subscribers, breaking automations, and resetting your sender reputation. Choose carefully once, and commit for at least 12 months before reconsidering.
Frequently Asked Questions
What is the best email marketing platform for small businesses in 2026?+
GetResponse is the best email marketing platform for small businesses in 2026. It offers the most complete feature set (email, automation, landing pages, webinars) at a competitive price point starting at $19/month. For businesses that need advanced automation specifically, ActiveCampaign is the better choice despite its higher cost.
Which email marketing tool has the best deliverability?+
In our 90-day test, GetResponse achieved the highest deliverability rate at 95.4%, followed by Klaviyo (94.6%) and ConvertKit (94.1%). Mailchimp had the lowest deliverability in our test at 91.2%. Deliverability depends on many factors including your sender reputation, list hygiene, and content quality.
Is Mailchimp still worth using in 2026?+
Mailchimp is worth using only if you need a free plan for under 500 contacts. On paid plans, it is more expensive than GetResponse and MailerLite while offering fewer features. Since the Intuit acquisition, pricing has increased and the free plan has become more restrictive. For growing businesses, GetResponse or ConvertKit offer better value.
How much should I budget for email marketing software?+
Most small businesses should budget $20-60/month for email marketing software. At 1,000 subscribers, expect to pay $13-29/month depending on the platform. At 10,000 subscribers, costs range from $29/month (ConvertKit) to $139/month (ActiveCampaign). The average ROI for email marketing is $42 for every $1 spent, making it one of the highest-return marketing channels.
Can I switch email marketing platforms without losing subscribers?+
Yes, you can migrate subscribers between platforms by exporting your list as a CSV and importing it into the new tool. However, you will lose automation workflows, email templates, and historical analytics. Your sender reputation may also be temporarily affected. Plan 2-4 weeks for a full migration and run both platforms in parallel during the transition.
