10 Best Loops.so Alternatives for 2026 (Priced at 5,000 Contacts)

SendHeron fits the SaaS team whose lifecycle email has never been properly built, and the team that has to answer "where is my customer data" to a European buyer. In the first case the setup drafts the suite and the visual sequence builder is where you edit it: triggers, delays and conditions that branch on tags or contact properties with AND and OR rules. In the second, the answer is Germany, an EU legal entity, and a DPA on request. Founders running several products get a workspace per product under one subscription, with unsubscribes kept per project and hard bounces suppressed across the account.

It is the wrong tool in three cases. It is not an agency tool: roles are account-wide, there are no per-workspace member permissions and so no client login. It has no push, SMS or in-app channel, so if Customer.io's cross-channel journeys are what you actually need, read that entry instead. And it does not sell above 200,000 contacts yet, so a list that is already past that has to look at Loops, Customer.io or Mailchimp.

Hosting, first. Loops's privacy policy says data is transferred to and processed in the United States, with Standard Contractual Clauses as the transfer mechanism; there is no EU option to switch on. SendHeron's answer is structural rather than contractual: an EU company, with contact data stored in Germany. The residency page says what can be proven and what cannot, in one table.

Second, the blank canvas. Loops gives you an excellent editor and an empty workspace; the lifecycle logic is yours to design. SendHeron starts from your website and hands you a drafted suite with the tag schema your developer has to wire, plus the snippets to do it. That is a different amount of work in the first week, and it is the difference most switchers notice first.

Export your subscribed contacts from Loops's Audience page, then upsert each one over the API with the tags your sequences trigger on; the Node SDK wraps the calls and the API reference states the rate limits to pace against. Load your unsubscribes as suppressions before you send anything, so nobody who opted out of Loops's mail hears from you by accident.

Templates paste in as HTML, and you can keep editing them as HTML or rebuild them in the block builder. Your loops themselves have to be rebuilt, because Loops and SendHeron model branching differently; the setup drafts a starting suite from your website and we help you map the old flows onto it during onboarding. Run both tools in parallel for the length of the trial, with new signups going into SendHeron and Loops draining down.

Customer.io suits the company with a growth or lifecycle team of its own, a mobile app that needs push, and a support function that will use in-app messaging. At that size the $100 floor is a rounding error and the depth (objects, segments over nested data, ad audience sync, reverse ETL on Premium) is the point.

It does not suit a two-person SaaS whose whole requirement is a welcome sequence and a win-back. You would be paying for channels you do not run and learning a data model built for objects and relationships you do not have. Loops itself, SendHeron or Bento cover that job at a fifth of the price.

The channel ceiling. Loops is email and only email; there is no push, no SMS and no in-app. If your product has a mobile app or an in-product surface you want to message on, Loops cannot follow you there and Customer.io can, from the same workflow.

The residency question, as a menu item. Loops has no EU option; Customer.io lists US or EU data centers on every plan. That makes it the second tool on this page that can answer a European buyer's data question with a location rather than a contract clause.

Profiles come in over Customer.io's API or a CDP integration, and the event schema is the real work: Customer.io is built around events and attributes, so map what Loops was sending as contact properties onto Customer.io attributes and what it was sending as events onto Customer.io events before you import anything.

Budget for the team, not the tool. The workflow builder is deep, and the reason most Customer.io migrations take weeks is deciding who owns each campaign, not moving the data. Use the startup program if you qualify; it removes the price question for a year.

Userlist suits B2B SaaS with team accounts, a customer success function, and a list that is already at or near 10,000 users, where the floor stops being a penalty. Its servers are in the United States, per its privacy policy, so it is not an answer to the residency question.

It does not suit a consumer or prosumer product with individual users, or any product under a few thousand users, where you would be paying $149 for capacity you do not fill. Bento, SendHeron or MailerLite cover a solo-user product for a fraction of it.

The per-person data model. Loops knows about contacts and their properties; it has no first-class notion of a company that several contacts belong to. If your lifecycle logic keeps needing "when the account does X" rather than "when this user does X", you are working against Loops's model and with Userlist's.

In-app messages. Loops is email only; Userlist can put a message inside your product from the same workflow, which for activation campaigns is often the channel that actually works.

Users and companies come in over Userlist's HTTP API and its client libraries, or through a CDP. Plan the company relationships before you import: the point of moving is the account model, and importing users without their companies recreates Loops with a higher bill.

Rebuild workflows against events. Userlist's triggers are event and property driven, so map each Loops trigger to a Userlist event first. Use the roadmapping session that comes with a new Basic account; it is the fastest way through the model.

Bento suits the small SaaS or creator business that wants marketing email and a light CRM in one place and does not want to think about the bill again for a long time. At $29 for 5,000 active users, it is cheaper than Loops from the first paid step, and it stays cheaper up the curve.

It does not suit a buyer with a residency requirement (hosting is not stated), and its transactional product is metered separately, so a SaaS that sends a lot of receipts and resets pays two lines. It also has no in-app or push channel.

The price at every step. Loops is $49 at 5,000 subscribers and $99 at 10,000; Bento is $29 at 5,000 and roughly $79 at 10,000 on its published per-user rate. The gap widens as the list grows, and Bento's active-user definition means a dormant chunk of your list does not count at all.

The missing CRM. Loops is an email tool with contacts; Bento adds a CRM, forms, popups and a chat inbox, so a small team can run its whole customer communication from one login rather than three.

Bento lists migration help on its pricing page, and for a Loops list that is the route to take: export subscribed contacts and tags, hand them over, and let the team import them. Suppress your unsubscribes first.

Rebuild the loops as Bento flows, and take the 30 days seriously: it is the longest trial on this page and long enough to run a real welcome sequence end to end before you commit.

Resend suits the developer-led product where every email is rendered by your own code and the marketing side is a handful of broadcasts a year. The SDKs, the docs and the developer experience are the best in the category, and under 1,000 contacts nothing here is cheaper.

It does not suit a team that wants lifecycle sequences with branching designed in a visual builder, or a team whose customer data has to stay in the EU. Automations exist and are metered per run; they are not the centre of the product the way they are for Loops, SendHeron or Customer.io.

Nothing on price under 1,000 contacts, and not much on the developer side: Resend is the tool most Loops users would have picked if they had wanted an API rather than a product. What you escape is contact-based pricing for transactional mail. Loops folds transactional into a contact price; Resend charges by email, so a product that sends many receipts to few people pays less.

What you do not escape is US data storage, and you give up the email editor and the loops themselves in exchange for an API. Be clear about which of those you are buying before you move.

Contacts import over the API into an audience, and templates become code (React Email, or your own HTML). Broadcasts replace campaigns; automations replace loops, with the run count in mind. The transactional side is the easy part and usually takes an afternoon with the SDK.

Keep the marketing free tier in mind as a stepping stone: under 1,000 contacts it costs nothing to run Resend beside Loops for a month and see whether the loss of the visual builder matters to you.

Plunk suits the developer or indie SaaS that wants the lowest possible per-email price and is comfortable with a younger, smaller product, and the team that wants to run its own instance for the data ownership. If your list is large and your sending is light, per-email pricing is the model that fits you, and Plunk has the cheapest rate on this page.

It does not suit a marketing team that wants a rich visual editor, a mature template gallery, or vendor support with an SLA; you are trading those for price and openness. And self-hosting means you own deliverability, upgrades and uptime, which is real work.

Contact-based pricing entirely. Loops charges for subscribed contacts and gives you unlimited sends; Plunk charges for sends and gives you unlimited contacts. For a product with a big, quiet list, the inversion cuts the bill by an order of magnitude.

Vendor lock, if you self-host. The hosted product still depends on Plunk, but the AGPL code means the day you want the data and the sending under your own roof, you can have it.

Contacts import over Plunk's REST API or its Node and Python SDKs; templates paste in as HTML. Rebuild loops as Plunk automations, which have the same triggers, delays and conditions shape, so the mapping is direct.

If you self-host, the migration is a deployment before it is a content move: stand up the instance, set up the sending domain and DNS, warm it, and only then bring the list across. Set a spend cap on the hosted plan before you send your first campaign.

Sequenzy suits the bootstrapped SaaS with a large list, a light sending schedule and a payment provider it wants automations to key off. The attribution against Stripe and the founder-run support are what its testimonials talk about, and the free plan is a real way to try it.

It does not suit a team that needs a stated data location, or one that sends heavily: at 300,000 emails a month it is $199, which is where contact-priced tools start to win back. It is also a small company, which some buyers count as a risk and some as a feature.

The subscriber count. Loops's bill rises with every subscribed contact whether you mail them or not; Sequenzy's rises only with what you send. A 25,000-contact list that mails monthly pays $199 on Loops and $29 on Sequenzy for the same month of email.

The single-channel ceiling, a little: Sequenzy's SMS add-on exists, though only with a North American number, and Loops has no SMS at all.

Contacts come in over the API, the CLI or a CSV; Sequenzy's own testimonials describe agents scripting the sync from another provider through its MCP server, which is a fair description of how a developer would do it. Load your unsubscribes first.

Rebuild loops in the automation builder, whose trigger set (events, tags, lists, inactivity) is a superset of what you are leaving, and connect Stripe before you build anything payment-driven, because that integration is the reason to be here.

MailerLite suits the founder or creator whose SaaS has a content side: a newsletter, a course, a landing page for every launch. If half your email is a newsletter and half is lifecycle, Power at $69 for 5,000 subscribers with unlimited sends is a strong price for both.

It does not suit a product whose lifecycle logic is event-heavy and API-driven. The automation builder is capable but general-purpose, transactional mail is a different product, and there is no notion of a company account. SendHeron, Loops or Customer.io fit that shape better.

Residency, again: MailerLite stores data in the EU where Loops does not. And the send cap on Comfort is the thing to compare honestly against Loops's unlimited sends: at 5,000 subscribers Comfort allows 50,000 emails a month, and if you need more, Power removes the cap for $20 more.

The feature gap runs the other way too. Loops has nothing like landing pages, paid newsletters or digital products; if those are on your roadmap, MailerLite has them today.

Import subscribers by CSV or API, with groups standing in for Loops's tags, and rebuild loops in the automation builder. Power's multiple triggers matter here: a Loops loop with several entry points becomes one MailerLite automation rather than several.

Decide on transactional before you move. If your product sends receipts and resets through Loops today, they need a home, and MailerSend is a second account with a second bill.

Brevo suits a business that wants SMS or WhatsApp in the same journeys as email, or that sends few emails to a large list and so benefits from volume pricing. It is a broad suite and a mature one.

It does not suit a developer-led SaaS that wants a tight contact-and-event model and an API-first workflow; it is built for marketers first. And the Starter plan is not a lifecycle tool at all, so compare against Standard.

The contact count, and the single channel. Loops bills per subscribed contact; Brevo bills per email, so a large quiet list is cheap. Loops is email only; Brevo puts SMS and WhatsApp on the same automation canvas.

The free tier shape is different rather than better: Brevo's free plan is a daily send limit rather than a contact ceiling, which suits a product that mails rarely.

Contacts come in by CSV or API into lists, with attributes standing in for Loops's properties. Rebuild loops as Standard-plan automations and wire your transactional sends to the SMTP relay or API.

Start on Standard, not Starter, for the trial of the lifecycle side; Starter has no automation, and evaluating it for that job wastes the trial.

Mailchimp suits a marketing team whose email is mostly campaigns and newsletters, that values the ecosystem, and that is likely to hire people who already know the tool. Above 250,000 contacts its bands keep going where several tools on this page stop.

It does not suit a SaaS that wants lifecycle sequences triggered by product events with real branching, or that cares about a residency answer, or that has accumulated unsubscribes it does not want to pay for. That is three of the reasons people left it for Loops in the first place.

Very little, on the axes that made you pick Loops. Standard at 5,000 contacts is twice Loops's $49, the sends are capped where Loops's are not, the automation is flow-point-limited where Loops's is not, and the hosting is the same country. The honest reason to go back is the ecosystem, not the product.

The one thing Loops cannot match is the audience size ceiling and the catalogue. If you need forty integrations and a template for everything, Mailchimp has them.

Import contacts by CSV into an audience, and archive rather than import your unsubscribes so they are not billed. Rebuild loops as Customer Journeys, keeping the flow-point cap on Standard in mind.

Check the contact band before you commit: at 5,001 contacts you cross into the $135 band, so a list sitting just above a boundary should be cleaned before the first invoice.
