Best Email marketing software of 2026

What is email marketing software

An email marketing platform stores your subscribers, gives you an editor to design campaigns, and handles sending at scale while managing unsubscribes and bounces for you. Most also include signup forms, automated sequences and reports on opens and clicks.

Any business that sells to people who don’t buy on their first visit benefits: online shops, course creators, consultants, SaaS companies and local services. Email is a channel you own, unlike social reach, so it rewards the effort over time.

How to choose

Pricing model

This is the biggest difference between tools. Most charge by the number of contacts, so a large list you rarely email gets expensive. Brevo prices by emails sent instead, which suits big lists with occasional sends. Match the model to how you actually email.

Automation and segmentation

Newsletters are the easy part. Revenue usually comes from automated sequences triggered by behaviour, and from sending the right message to the right segment. ActiveCampaign is strong here, with conditional workflows and a built-in CRM.

Deliverability tools

Check for easy domain authentication setup (SPF, DKIM, DMARC), list hygiene features and clear bounce handling. Every reputable tool covers the basics; what differs is how much guidance they give you.

Editor and templates

A drag-and-drop editor with mobile-friendly templates saves hours. If you prefer plain-text emails that feel personal, make sure the tool doesn’t force heavy designs on you.

CRM and sales handoff

If you have a sales team, consider a platform where email and CRM share contact records. HubSpot CRM is a common starting point because the CRM itself is free.

Mistakes to avoid

• Importing a cold or bought list. It hurts deliverability and may break the tool’s terms. Only email people who opted in.
• Skipping domain authentication. Set it up before your first send, not after emails start landing in spam.
• Paying for contacts who never open. Clean inactive subscribers regularly, especially on contact-based pricing.
• Judging success by opens alone. Privacy features make open rates unreliable; watch clicks, replies and sales.
• Only sending newsletters. A simple welcome sequence often does more than months of broadcasts.
