1. Brevo, Best Overall for Small Business
Why small teams choose it
- Volume pricing: you pay for emails sent, not contacts stored
- Built-in CRM, no separate tool to buy or sync
- Email, SMS, and WhatsApp in one place
- Marketing automation included free
Pricing model: Brevo pricing depends on email volume, feature tier, branding, automation, analytics, SMS, WhatsApp, and transactional email. Verify current free-plan and paid-plan limits before moving production sends.
2. MailerLite, Best for Simplicity
Clean interface, fast to learn, fair pricing model. Best for businesses that want a focused email tool and nothing more. Limitation: subscriber-based limits and no native SMS or WhatsApp.
3. Mailchimp, Most Familiar Brand
Large template library and strong brand recognition. Reasonable if you are comfortable with contact-based pricing as you scale; otherwise see Mailchimp alternatives.
4. Kit, Best for Creators
Built for newsletters, bloggers, and course sellers (formerly ConvertKit). Best for creators selling digital products. Limitation: creator-first design and automation gates may not fit a local business or ecommerce store.
5. Constant Contact, Best for Local and Event Businesses
Event management and local-business features. Best for local businesses running events. Limitation: trial-first path and lighter automation than Brevo or MailerLite.

Frequently Asked Questions
Which email marketing software should small businesses compare in 2026?
Compare Brevo for email, CRM, SMS, WhatsApp, and volume-based pricing; MailerLite for simplicity; Mailchimp for familiarity; Constant Contact for local and event businesses; ActiveCampaign for deeper automation; and HubSpot for CRM-suite alignment.
How much should a small business spend on email marketing?
Start with a free or trial path, then model the paid cost from contacts, sends, automation, branding, seats, SMS or WhatsApp, and CRM needs. Entry prices rarely predict the bill once the list and workflows grow.
Do I need email marketing software or can I use Gmail?
Use dedicated software. Personal inboxes are not built for unsubscribe handling, templates, analytics, authentication, segmentation, or bulk sending. Sending marketing email from a personal mailbox can damage trust and deliverability.
Which free plan lasts longest as I grow?
Choose the free or trial path whose limits match your likely first year, not only your first campaign. Check contacts, sends, branding, automation, and CRM features.
Is per-contact or volume pricing cheaper for a small business?
Volume pricing (Brevo) is usually cheaper once you have a list with many infrequent buyers, since dormant contacts cost nothing to store. Per-contact pricing favors small, highly active lists.
Can one tool cover email, SMS, and a CRM at this budget?
Yes. Brevo bundles email, SMS, and CRM in one platform, which removes the operational cost of stitching separate tools together.
What about ActiveCampaign for a small business?
It is powerful but has no free plan and prices per contact. See [ActiveCampaign alternatives](/blog/best-activecampaign-alternatives/) for lower-cost options with similar automation.
