# Best for email marketing Explore MailerLite for newsletters and welcome sequences, Brevo for send-based billing with a larger, less active list, and Mailchimp for ecommerce behavior and branching customer journeys. Reference workload: 2,000 subscribers, four monthly campaigns and a two-email welcome sequence for 100 new subscribers: about 8,200 sends. We also consider a 5,000-contact list with infrequent sends. Content updated: 2026-09-28. Research: GPT-6 Astra and Claude Opus 5.5. Execution: completed. Evidence coverage: partial. Research cutoff: 2026-09-27T23:16:52.790325+00:00. ## MailerLite For newsletters, welcome sequences and basic segmentation, consider MailerLite. Mailercloud describes welcome sequences, conditional branches and custom-field filtering. Start with a two-email welcome flow to assess setup and ongoing maintenance. Confirm that the current plan supports 2,000 recipients in one day and 8,200 monthly sends. Do not rely on older free allowances or plan prices. Decision: Check current allowances. Evidence: limited.

Delay and exit settings were not specified. Automation allowances differ by plan, and no workflow was tested. — Recorded in Claude Opus 5.5 research (c-ml-welcome). Sources: [Mailercloud](https://www.mailercloud.com/blog/mailerlite-vs-mailchimp), [Mailchimp](https://mailchimp.com/resources/mailchimp-vs-mailerlite/), [GetResponse](https://www.getresponse.com/blog/getresponse-vs-mailerlite). - Mailercloud describes conditional branching in MailerLite automations. The required plan and availability of click-event conditions were not specified. — Recorded in Claude Opus 5.5 research (c-ml-branch). Sources: [Mailercloud](https://www.mailercloud.com/blog/mailerlite-vs-mailchimp). - Mailercloud, Moosend and GetResponse describe MailerLite segmentation using contact fields, engagement, location or other attributes. Availability across plans was not established. — Recorded in Claude Opus 5.5 research (c-ml-segment-fields).

MailerLite describes Brevo's send-based pricing. It is worth calculating for infrequent campaigns, while also checking contact-storage limits. The reported free-plan limit of 300 emails a day cannot cover a same-day campaign to 2,000 people. Check paid contact limits, daily sending capacity and automation together. Decision: Price your actual workload. Evidence: limited. [Cite this recommendation](https://bestforwhat.com/best-for-email-marketing/#product-brevo) ### Supporting evidence - Brevo Free is described as allowing 300 email sends per day. That limit would not cover a same-day send to 2,000 or 5,000 contacts; paid plans require separate checking. — Recorded in GPT-6 Astra research (c1). Sources: [MailerLite](https://www.mailerlite.com/brevo-alternative). - Brevo is described as billing by send volume while also imposing contact allowances. Both list capacity and sending volume need checking; this does not establish the lowest cost. — Recorded in GPT-6 Astra research (c2). Sources: [MailerLite](https://www.mailerlite.com/brevo-alternative). ## Mailchimp For marketing workflows that need ecommerce behavior triggers, branching journeys and more detailed segments, consider Mailchimp. Mailercloud describes multi-step branches, behavior triggers and custom-field segmentation. Build a real example of your customer journey to test the fit. Automation varies by plan, and billing can include unsubscribed and non-subscribed contacts. Audit your list before confirming the plan and send allowance. Decision: Check the automation tier. Evidence: limited. [Cite this recommendation](https://bestforwhat.com/best-for-email-marketing/#product-mailchimp) ### Supporting evidence - Mailchimp is described as counting subscribed, unsubscribed and non-subscribed contacts for billing. Contact statuses need checking before estimating cost. — Recorded in GPT-6 Astra research (c3). Sources: [MailerLite](https://www.mailerlite.com/mailchimp-alternative). - Mailchimp Standard is described as allowing monthly sends equal to 12 times the contact allowance. Daily limits and the two-step welcome workflow were not confirmed, so this alone does not establish scenario fit. — Recorded in GPT-6 Astra research (c4). Sources: [MailerLite](https://www.mailerlite.com/mailchimp-alternative). - Mailercloud describes paid Mailchimp Customer Journey Builder branching and ecommerce behavior triggers; Omnisend describes Shopify triggers on Standard. Click-event branching was not explicitly confirmed. — Recorded in Claude Opus 5.5 research (c-mc-behavior-triggers). Sources: [Mailercloud](https://www.mailercloud.com/blog/mailerlite-vs-mailchimp), [Omnisend](https://www.omnisend.com/blog/brevo-vs-mailchimp/). - Mailercloud describes Mailchimp segmentation using engagement, purchases, website activity and custom fields; GetResponse and Moosend also describe tags or audience groups. The plan required for advanced segmentation was not established. — Recorded in Claude Opus 5.5 research (c-mc-segment-fields). Sources: [Mailercloud](https://www.mailercloud.com/blog/mailerlite-vs-mailchimp), [GetResponse](https://www.getresponse.com/blog/mailchimp-vs-getresponse), [Moosend](https://moosend.com/blog/mailerlite-vs-mailchimp/). ## Research and sources Research runs have finished.
