How We Compare Email Tools

Sequenzy writes its comparison, alternatives and “X vs Y” pages. Sequenzy is our own product, and it appears on these pages, usually highlighted, with links to sign up. Read every page with that in mind.

Most of them are written by Nic Polotnianko, who built and ran SaaS products, including BlogToPin, before Sequenzy, and sent a lot of their onboarding, billing and marketing email. Today Sequenzy sends email for more than 5,000 customers, which is where most of the practical detail comes from. More about Nic.

We try to make that bias easy to check: claims about other tools link to the vendor's own documentation or pricing page, and where Sequenzy falls short, the page says so.

• Roundups. Ranked lists for one job, with a short answer at the top, a comparison table, free plan limits, and the price at 10,000 contacts where the tool is priced by list size. For example: email marketing software, email automation software, transactional email services, newsletter platforms, free email marketing tools and affordable email marketing tools.
• Sequenzy vs one tool (all Sequenzy comparisons). Where Sequenzy fits, where the other tool is the better choice, and the price of each at the same sending volume. For example: Sequenzy vs Mailchimp and Sequenzy vs Klaviyo.
• Tool vs tool (all head-to-head comparisons). Two other tools side by side: price at 10,000 subscribers, feature tables, which one wins each use case, and a migration checklist. For example: Constant Contact vs Mailchimp and HubSpot vs Mailchimp.
• Alternatives lists (all alternatives lists). Why people leave a tool, the replacements with editorial scores, the price comparison, and when staying is the right call. For example: Mailchimp alternatives and Klaviyo alternatives.
• Pricing guides. One tool's plans, prices by list size and the limits that push you to the next plan, each linked to the vendor's pricing page. For example: Mailchimp pricing, HubSpot pricing, Klaviyo pricing and ActiveCampaign pricing.

Entry prices hide how a tool scales. Most email tools price by contact count, and by 10,000 contacts nearly every list has left the free plan and the gap between tools is large: on the same page a tool can be the cheapest at 500 contacts and one of the most expensive at 10,000.

Where a tool bills by emails sent instead of contacts, as Sequenzy does, the page compares the plan that covers 10,000 contacts at a typical sending volume and says so. Pricing guides also show smaller list sizes, because that is where most people start.

• Pricing is checked against each vendor's public pricing page. Pages show the date it was checked and link to the page it was checked against.
• API, CLI and MCP access and the data export tables come from vendor developer docs, API references, MCP tool lists, help centers, changelogs and the vendor's GitHub. Each answer links to the page that confirms it. If we could not confirm something, the table says “Not confirmed” rather than guessing.
• An MCP server counts as official only when the vendor publishes it for that product and it can act on your account. Servers for a different product from the same vendor, servers that only search documentation, and apps that only run inside Claude or ChatGPT are labelled as such.
• Sequenzy's own facts, such as prices, features and MCP tools, come from the same data and code that run the product, so they update when the product changes.

• User reviews are quoted from public review sites such as Trustpilot and G2 and link to the original. We do not write or edit them. Where we show two, we pick the highest and lowest rated so you see both sides.
• A tool's Trustpilot score is shown only when its profile has at least 20 reviews.
• Sequenzy's rating is its 4.9 rating on G2 from 8 reviews. Customers' own words are in the customer stories.

Star scores for other tools on alternatives lists are our editorial scores, not an average of user reviews. They reflect how well each tool fits the use case the page is about. The order of each list is also our editorial choice, and Sequenzy is placed where we think it fits.

A few links to other tools are referral links: currently Brevo, MailerLite, Beehiiv and SMTP2GO. If you sign up through one, Sequenzy may earn a commission. These links are marked as sponsored for search engines. All other links to vendors are plain links.

Each page shows an “Updated” date: the later of when its text last changed and when the tool data on it was last checked. Pricing and product facts change often, so check the linked source before making a decision that depends on one detail.

If something is wrong or out of date, including if you work at one of the companies we cover, email nic@sequenzy.com with the page and a source, and we will fix it. You can also see how we handle data in our security overview.
