TL;DR

• Free tiers (MailerLite up to 1k, Kit up to 10k) work for small lists — no infrastructure needed.

• Self-hosted with MisarMail + Amazon SES costs ~$25–35/month for 100k emails vs $800+/month on Mailchimp.

• Amazon SES alone is cheapest at $0.10/1,000 emails but gives you no UI — you need a campaign layer on top.

• Gmail is not a bulk email option at scale — ToS violation and high blacklist risk.

• Deliverability depends on SPF/DKIM/DMARC, clean lists, and consistent sending cadence regardless of platform.

How to Send Bulk Email for Free (or Nearly Free) in 2026

Sending bulk email for free sounds like a trap — and often it is. Most "free" bulk email tools are either spam services, severely limited trial accounts, or platforms collecting and monetizing your subscriber data as the real product.

But there are legitimate, sustainable ways to send bulk email at zero or near-zero cost. This guide covers all of them honestly, including what the real limits are.

What "Bulk Email" Actually Means

Bulk email is any email sent to a large list simultaneously — newsletters, promotional campaigns, product announcements, re-engagement sequences. This is distinct from transactional email (receipts, password resets, notifications), which uses different infrastructure.

For bulk email to work:

• Recipients must have consented to receive it (legally required in most jurisdictions)

• Your sending domain must have SPF, DKIM, and DMARC records configured

• You need a way to handle unsubscribes automatically

• Bounce handling must be in place to protect sender reputation

Without these in place, "free" bulk email quickly becomes spam — and spam quickly becomes blacklisted.

Option 1: Free Tiers on SaaS Platforms

The quickest path to free bulk email is using the free tier of an established platform.

Brevo (formerly Sendinblue) — 300 emails/day free

Brevo offers 300 emails per day (roughly 9,000/month) with unlimited contact storage. No credit card required. The Brevo logo appears in email footers on free accounts.

Best for: Small newsletters, test campaigns, early-stage products with limited lists.

Realistic ceiling: At 300 emails/day, you can reach your entire list once a month if it's under 9,000 people. For weekly sends, that's about 1,200 subscribers.

MailerLite — Free up to 1,000 subscribers, 12,000 emails/month

MailerLite's free plan is one of the most generous in the industry. You get 1,000 subscribers, 12,000 emails/month, automation workflows, landing pages, and the full campaign builder. No credit card required.

Best for: Newsletters and small business marketing up to 1,000 subscribers.

Realistic ceiling: Once you hit 1,001 subscribers, you need a paid plan starting at $9/month.

Mailchimp — Free up to 500 contacts

Mailchimp's free plan has been progressively restricted. Currently it caps at 500 contacts, 1,000 emails/month, and basic features. The platform pushes hard to upsell.

Worth mentioning for completeness, but not a strong option compared to MailerLite or Brevo at this tier.

Kit (formerly ConvertKit) — Free up to 10,000 subscribers

Kit's free plan is remarkable: unlimited landing pages, unlimited broadcast emails, and basic automations for up to 10,000 subscribers. The catch is that you can only send broadcasts (no automation sequences on free), and Kit's pricing jumps significantly once you exceed 10k.

Best for: Creator-focused newsletters that want room to grow before paying.

Option 2: Self-Hosted Email — Near-Zero Cost at Any Scale

Self-hosted email marketing isn't free upfront — you need a server — but the per-email cost quickly approaches zero at scale.

The Cost Structure

VPS server: $5–20/month (DigitalOcean, Hetzner, Vultr)

SMTP relay: Amazon SES charges $0.10 per 1,000 emails. Sending 100,000 emails costs $10.

Domain: $10–15/year if you don't have one

Total for 100,000 emails/month: approximately $25–35/month.

Compare that to Mailchimp Standard at 100k subscribers: $800+/month.

Setting Up Self-Hosted Email with MisarMail

MisarMail is deployable to any VPS. The setup process:

1. Provision a VPS (2GB RAM minimum recommended)

2. Point your domain's DNS to the server

3. Deploy MisarMail via Docker Compose (one command)

4. Configure SPF, DKIM, and DMARC DNS records

5. Connect an SMTP relay (Amazon SES, Mailgun, Postmark)

6. Import your subscriber list

Once running, you can send unlimited emails limited only by your SMTP relay rate limits — and those can be increased on request.

The Hidden Costs of Self-Hosted

Be honest with yourself about the tradeoffs:

• Initial setup takes time (30–60 minutes for first-timers)

• You're responsible for server maintenance and uptime

• Deliverability is your responsibility — you need to monitor bounce rates, set up feedback loops, and respond to complaints

• If something breaks at 2 AM, you're the on-call engineer

For teams without technical resources, a SaaS free tier is likely the right starting point. For teams with developers who want to own their infrastructure, self-hosted is dramatically cheaper at scale.

Option 3: Amazon SES Direct (Technical Users Only)

Amazon SES is the cheapest SMTP relay available at $0.10/1,000 emails. You can use it directly as a bulk email service by building or using an open-source campaign manager on top of it.

What you get: Extremely low sending costs, excellent deliverability when configured correctly, full API access.

What you don't get: Any kind of user interface, campaign management, subscriber management, or analytics. SES is an SMTP relay, not an email marketing platform.

For technical users who want to build custom email workflows, SES is a building block. For most people who want to "send a newsletter," SES alone isn't enough — you need a layer on top.

Option 4: Google Workspace (Transactional/Small Lists Only)

Google Workspace includes Gmail, and Gmail has a daily sending limit of 2,000 emails/day per account (500/day on the free tier). Some people use this for small list broadcasts.

This approach has serious limitations:

• Gmail isn't designed for bulk email and will flag your account if you send marketing email at volume

• No unsubscribe management

• No analytics

• No template builder

• Terms of service prohibit using Gmail for commercial bulk email

Don't do this at scale. It's a path to getting your domain blacklisted.

The Deliverability Reality Check

Regardless of which option you choose, bulk email success depends on list quality and sending practices:

Confirmed opt-in: Use double opt-in (email confirmation after signup) to build a list of engaged subscribers. It reduces list size but dramatically improves open rates and reduces spam complaints.

Regular sending cadence: Inconsistent senders get lower inbox placement. If you send monthly, be consistent. Inboxes treat irregular sending as a signal of lower quality.

Remove cold subscribers: Anyone who hasn't opened in 6+ months is hurting your deliverability more than they're helping your metrics. Regular list cleaning is essential.

Monitor feedback loops: Gmail, Yahoo, and Outlook send complaint reports when users mark your email as spam. Process these and suppress complainers immediately.

Avoid spam trigger words: Subject lines with "FREE!!!" or "WINNER" and bodies with excessive capitalization or image-only content will hit spam filters regardless of your infrastructure.

Which Option Should You Choose?

The "best" free option depends entirely on your list size, sending frequency, and technical capability. There is no free lunch — but there are options that come close.
