Email marketing for small business works best with a permission-based audience and a schedule you can maintain. These editorial picks prioritize straightforward campaigns, send-volume comparison, creator newsletters, commerce data and more involved automation. Check current limits before importing contacts or connecting a store.

Email marketing for small business: the shortlist

1. Mailchimp

Mailchimp is an email marketing platform for campaigns and audience management.

Strengths: templates and guided creation give a small team an approachable starting point.

Limitations: free contact and sending allowances are restricted; growing lists and advanced automation require a paid-plan comparison.

Pricing model: a verified free entry plan and paid offerings influenced by contacts, features and send allowances.

Best for: beginners starting regular permission-based campaigns.

2. Brevo

Brevo combines email campaigns with SMS and transactional messaging options.

Strengths: email-volume-led pricing can suit a contact list larger than regular campaign sending needs.

Limitations: its free tier has a daily send cap and requires account approval. SMS, contacts and advanced features need a separate check.

Pricing model: free and paid tiers with send-volume, contact, feature and channel conditions; not simply unlimited contacts or pure pay-per-send.

Best for: small businesses comparing campaign and transactional email together.

3. Kit

Kit, formerly ConvertKit, is an email platform for creators and newsletter businesses.

Strengths: newsletter workflows, recommendations and digital-product tools suit an audience-led business.

Limitations: advanced automations, sequences and earning from Paid Recommendations depend on paid plans. Direct pricing access was blocked during this review.

Pricing model: official indexed help describes a free Newsletter plan and paid tiers; confirm current access and allowances directly. No numerical free limit is asserted here.

Best for: creators developing newsletters and digital products.

4. Klaviyo

Klaviyo is a marketing platform designed around customer and commerce data.

Strengths: segmentation, automation, store connections and attributed-revenue reporting support commerce-led campaigns.

Limitations: results depend on useful customer and event data; attribution does not prove every reported sale was caused by email.

Pricing model: a verified limited free tier and paid offerings based on active profiles, sends and channel allowances.

Best for: online stores using purchase and browsing signals responsibly.

5. ActiveCampaign

ActiveCampaign is an email platform centered on automation and segmentation.

Strengths: visual workflows and behavior-based follow-ups support more involved customer journeys.

Limitations: workflows take time to configure and maintain. Sales CRM uses modular offerings or add-ons; do not assume it is bundled into a higher email tier.

Pricing model: paid plans and a trial, not a permanent free plan; contacts, tier, channels and add-ons affect cost.

Best for: teams with recurring automation requirements beyond a simple newsletter.

Getting started in 4 steps

  1. Use permission-based contacts. Import people who opted in; do not buy or scrape lists.
  2. Add a signup form. Explain what you will send and retain appropriate permission records.
  3. Create a welcome automation. Confirm expectations and test links before enabling it.
  4. Include required sender details. US commercial email needs a valid physical postal address and an effective unsubscribe mechanism, among other CAN-SPAM obligations. These two elements alone do not establish full compliance. Check applicable privacy and electronic-marketing laws for other audiences, including GDPR territorial scope, lawful basis and consent requirements where relevant.

The FTC CAN-SPAM guide was blocked during this check, so no unverified link is inserted. Permission-based platform practices should not be confused with a claim that CAN-SPAM is an opt-in statute.

A sustainable sending schedule

A biweekly newsletter is a possible starting example, not a rule for every business. Adjust to subscriber expectations, engagement, unsubscribes and complaints. Automations should deliver relevant follow-ups, not increase unsolicited volume.
