Cheapest email marketing software for small businesses

Low-cost email marketing platforms for small businesses with an opted-in list, ordered by the lowest paid price each vendor publishes. Most of them price by list size, so the entry price is for a small list (500 to 1,000 contacts) and rises as you grow. Every price comes from the vendor's own pricing page.

For small teams: see every small team friendly sales tool (free plan or free trial, self-serve, $50/mo or less) and your first sales tool stack for under $100/month.

How this list works: Ordered by lowest listed paid entry price (annual billing where the vendor shows it). The 'Priced by' column shows the list size or send volume each entry price covers. Pricing verified against vendor pages (latest check 2026-11-12). No placement here is paid. Methodology.

FAQ

What is the cheapest email marketing software?

On published entry prices: Moosend Pro is $7/mo billed annually ($9 monthly) at its smallest contact tier, Brevo Starter $8.08/mo billed annually (from 5,000 emails a month), Constant Contact Lite $10.20/mo billed annually, MailerLite Comfort $10.80/mo billed yearly at 500 subscribers and AWeber Lite $12.50/mo billed annually at 500 subscribers.

Which cheap email marketing tools have a free plan?

Kit's free plan covers up to 10,000 subscribers, MailerLite's 250 subscribers, and Mailchimp and GetResponse list free plans with limited features. Moosend has a 30-day free trial instead, and AWeber and GetResponse list 14-day trials of their paid features.

Is the cheapest plan still cheap as my list grows?

Not always. Most of these tools price by subscribers or contacts, so compare at your own list size on each vendor's pricing page. Brevo prices by emails sent instead, which can cost less for a large list you email rarely.

Can I use these tools for cold email?

No. Email marketing platforms are for opted-in subscribers. For outbound prospecting, use a cold email tool with separate sending mailboxes; see our cold email software for small business guide.
