| Best for | Teams that need multi-branch, behaviour-based email automation beyond what Mailchimp or MailerLite offer; B2B and non-ecommerce companies leaving HubSpot mainly for email marketing; Businesses with modest, actively mailed lists | SaaS and app teams whose lifecycle messaging is driven by in-product events; Teams with clean event data and developer time to maintain it; Products needing segmentation across distinct audiences, such as two-sided marketplaces |

More than half of the 68 comments are promotional: plugs for competing tools, a vendor reply, and a cluster of near-identical praise in Feb and Mar 2026 repeating the same abandoned-cart and automation-builder talking points. Among the rest, users consistently rate its automation builder as more capable than Mailchimp, Brevo or MailerLite for multi-branch workflows, and see it as a cheaper HubSpot alternative for email. The main trade-off is cost at scale: billing is by stored contacts rather than sends, users describe steep price jumps as lists grow, and two say removing old contacts to cut the bill is deliberately slow.
Users like
- Automation builder handles complex, multi-branch and behaviour-based workflows better than Brevo, Mailchimp or MailerLite[1][2][3][4][5]
- Users moving off HubSpot find comparable email marketing power for noticeably less money, with CRM features built in[1][2][3]
- Rated well for deliverability, and one user notes its reporting filters out bot clicks and Apple opens[1][2][3]
Users complain about
- Billing scales with stored contacts, not sends, so costs climb steeply as a list grows; users call it expensive at scale and note recent price increases[1][2][3][4][5][6][7]
- Removing old contacts to cut the bill is hard: one user says they are not allowed to delete contacts, another describes an archive-then-delete process that still needs support's sign-off[1][2]
Independent users see Customer.io as the event-driven lifecycle tool to pick when product usage defines who gets what, and several suggest making it the core orchestration layer with a lighter CRM beside it. The trade-off is effort and cost: users say event tracking needs a developer for most changes, costs climb as the list grows, and pairing it with HubSpot leaves you babysitting lifecycle-stage sync. Much of the discussion is recommendations rather than first-hand reports, and 8 of 32 comments were promotional, including an AI-generated reply that leaked its own prompt and plugs for Courier, Yonoma and Pulse for Reddit.
Users like
- Handles behavior-driven lifecycle orchestration across email, push and in-app well, so users recommend making it the core engagement layer when app events drive lifecycle[1][2][3][4][5]
- Recommended for advanced segmentation and automation beyond entry-level ESPs, including tagging separate audiences like clinics and end users in a marketplace[1][2][3]
- Long-term users say it is powerful and works well once running; a two-year user who moved off Pardot called it the best tool in their stack[1][2]
- Seen as the least expensive option among SaaS-oriented lifecycle platforms, with Braze and Iterable as tools to graduate to[1]
Users complain about
- Setup is slow and event tracking usually needs a developer; workflows, segments and behavioral campaigns take time to build[1]
- Costs rise as the list grows, and one freemium startup found roughly $1K a month too much and built an internal tool instead[1][2]
- Running it alongside HubSpot means fragile lifecycle-stage sync and logic maintained twice; one team said failed webhooks left the two tools disagreeing on a contact's stage[1][2][3]
- Editor annoyances: broadcast emails don't autosave, causing lost work, and a workflow's goal is a separate step[1][2]
