Choosing between the different email marketing software<\/strong> options seems simple until you start reading the fine print. They all promise beautiful templates, automations and statistics. But the differences show up when you look at how many emails you can actually send, to how many contacts, and who answers you when something goes wrong.<\/p>\n\n

In this guide we explain what good email marketing software should have, compare the current free plans of the most widely used tools in Spain and help you decide based on your situation. No inflated rankings.<\/p>\n\n

Quick answer:<\/strong> the most widely used email marketing tools are Mailrelay, Brevo, Mailchimp, MailerLite, Mailjet, Acumbamail and Klaviyo. If you’re looking for a generous free plan, Mailrelay lets you send up to 80,000 emails a month to 20,000 contacts, with no ads in your emails and with human support. Brevo stands out for storing lots of contacts, although it limits sending to 300 emails a day. Mailchimp and MailerLite have cut back their free plans significantly in 2026.<\/p><\/blockquote>\n\n

What is email marketing software?<\/h2>\n\n

Email marketing software is a platform that lets you create, send and measure email campaigns to a list of subscribers. It runs in your browser, so you don’t need to install anything.<\/p>\n\n

The difference from sending from Gmail or Outlook is huge. Specialized software handles unsubscribes automatically, spreads out sends so servers aren’t overloaded, authenticates your domain and tells you who opened, who clicked and who bounced. It also protects your sender reputation, which is ultimately what decides whether you reach the inbox or the spam folder.<\/p>\n\n

And there’s something that’s often overlooked: deliverability<\/a> depends as much on you as on the tool. Good software helps, but it can’t work miracles with a purchased list.<\/p>\n\n

What good email marketing software should have<\/h2>\n\n

Before comparing brands, it’s worth being clear about what you’ll need six months from now, not just today. Many companies choose based on the interface and find out too late that the free plan falls short or that support is only available in English and by email.<\/p>\n\n
