Email marketing is still one of the most powerful channels for reaching customers, nurturing leads, and driving conversions — and you don’t need to spend a fortune to do it well. Whether you’re a student building your first mailing list, a freelancer marketing your services, or a small business owner in India trying to stay in touch with customers, there are several excellent free email marketing tools that can handle the job beautifully.
In this comparison, I’ve researched and compared four of the most popular free email marketing platforms — Mailchimp, Brevo (formerly Sendinblue), Zoho Campaigns, and Sender — to help you figure out which one makes the most sense for your needs in 2026.
Quick Comparison: Free Plan Limits at a Glance
Before diving into the details, here’s a quick overview of what each platform offers on their free tier:
- Mailchimp: 500 contacts, 1,000 emails/month
- Brevo: Unlimited contacts, 300 emails/day (~9,000/month)
- Zoho Campaigns: 2,000 contacts, 6,000 emails/month
- Sender: 2,500 contacts, 15,000 emails/month
Already, you can see that Mailchimp’s free plan has become quite restrictive compared to where it was a few years ago. Let’s look at each platform in depth.
1. Mailchimp — The Established Name
Mailchimp is the name most people know when they think of email marketing. It’s been around since 2001 and has a polished interface, but its free plan has shrunk considerably over the years.
What You Get for Free
- 500 contacts and 1,000 emails per month
- Drag-and-drop email builder
- Basic email templates
- Single-step automations (like a welcome email)
- Mailchimp branding on emails
Where It Falls Short
The 500-contact limit is genuinely restrictive in 2026. You’ll hit it quickly if you’re actively growing your list, and the upgrade to a paid plan starts at around $13/month for 500 contacts — which feels steep for what you get. Multi-step automation sequences are locked behind paid plans, which is frustrating if you want anything beyond a basic welcome email.
Best For
Absolute beginners who want the most beginner-friendly interface and don’t plan to grow beyond a very small list quickly. Also suitable if you’re testing the waters and want brand recognition in your tool stack.
2. Brevo (formerly Sendinblue) — Best for High Email Volume
Brevo rebranded from Sendinblue in 2023 and has continued to grow as one of the most capable free email marketing platforms available. Its standout feature is the unlimited contacts on the free plan — which is genuinely unusual in this space.
What You Get for Free
- Unlimited contacts
- 300 emails per day (approximately 9,000/month)
- Drag-and-drop email editor
- Transactional emails
- Basic marketing automation (welcome emails, contact list workflows)
- SMS marketing (paid credits)
- Brevo branding on emails
Where It Falls Short
The 300 emails/day cap means you can’t do large list blasts on the free plan. If you have 5,000 contacts and want to send a newsletter, it’ll take about 17 days to reach everyone — which doesn’t work for time-sensitive campaigns. Also, advanced segmentation and A/B testing require paid plans.
Best For
Small businesses and freelancers with a growing contact list who send email campaigns less frequently. Also excellent for transactional email use cases (order confirmations, booking reminders) where volume per contact is low.
3. Zoho Campaigns — Best for Zoho Ecosystem Users
Zoho Campaigns is part of the broader Zoho suite, which includes CRM, books, projects, and more. If you’re already using Zoho for your business, Zoho Campaigns is a natural fit — and it integrates tightly with Zoho CRM for contact management.
What You Get for Free
- 2,000 contacts and 6,000 emails/month
- Pre-built email templates
- Basic autoresponders
- List management and segmentation
- Integration with Zoho CRM, Zoho Forms, and other Zoho apps
Where It Falls Short
The interface feels less polished than Mailchimp or Brevo, and the learning curve is steeper. Advanced automation workflows and A/B testing require moving to a paid tier. The free plan is also limited to a specific number of campaigns per month, so it’s less flexible for high-frequency senders.
Best For
Businesses already using the Zoho ecosystem, or those who need decent contact limits and CRM integration without paying for it.
4. Sender — Best Free Plan Overall for Growing Lists
Sender is the least well-known tool on this list, but it consistently offers the most generous free plan in 2026. If you’ve never heard of it, you’re not alone — but Indian marketers and bloggers are increasingly discovering it as a Mailchimp alternative.
What You Get for Free
- 2,500 contacts and 15,000 emails/month
- Drag-and-drop email and newsletter builder
- Basic automation workflows (welcome, birthday, cart abandonment)
- Pop-up forms and landing pages
- Analytics and reporting
- 24/7 email and chat support
- No Sender branding on emails (on free plan)
Where It Falls Short
Sender’s template library is smaller than Mailchimp’s. Advanced segmentation and behaviour-based automation are limited on the free tier. It also has less brand recognition, which matters if you’re recommending it to a team or client who wants familiar tools.
Best For
Bloggers, content creators, and small business owners who want the most generous free plan without branding restrictions. If you’re growing a newsletter or e-commerce list and don’t want to pay yet, Sender is currently the best-value free option.
Head-to-Head: Which Tool Wins for Indian Users?
For small contact list (<500 people)
Mailchimp works fine, but Sender gives you more room to grow without switching platforms.
For larger lists with infrequent sending
Brevo wins — unlimited contacts with 9,000 emails/month is excellent for monthly newsletters to large audiences.
For Zoho CRM users
Zoho Campaigns is the clear choice — tight integration means no data sync headaches.
For the most flexible all-rounder on a free plan
Sender offers the best combination of contacts (2,500), email volume (15,000/month), automation, and no forced branding.
Features That Matter for Indian Businesses Specifically
A few things worth noting from an Indian context:
- INR pricing: Brevo and Zoho Campaigns display pricing in INR, which is helpful for budget planning without currency conversion surprises.
- Deliverability in India: All four tools have solid deliverability rates. Brevo has a particularly strong transactional email infrastructure if you’re sending order or booking confirmations.
- GST invoicing: Zoho Campaigns (being an Indian company) provides proper GST-compliant invoices for paid plans — a significant advantage for businesses that need to claim input tax credit.
- Regional language support: All four platforms support Unicode, which means you can write email content in Hindi, Tamil, Telugu, and other Indian languages without issues.
The Bottom Line: Which One Should You Choose?
Here’s the honest summary:
- If you want the most generous free plan overall: Sender
- If you have a large contact list and send infrequently: Brevo
- If you’re already in the Zoho ecosystem: Zoho Campaigns
- If you want the most polished beginner experience: Mailchimp (but know the limits)
For most Indian students, freelancers, and small business owners starting out in 2026, I’d point you toward Sender first. The free plan is genuinely useful, there’s no forced branding on your emails, and the 15,000 monthly email limit gives you real room to run campaigns before you need to upgrade.
If your list grows beyond 2,500 or you need more advanced automation, that’s the right moment to evaluate paid plans — at which point the pricing and feature sets shift considerably, and platforms like ActiveCampaign, ConvertKit, or even Mailchimp’s paid tiers become worth comparing.
