Coste total de propiedad

Coste a 3 años en tres escenarios reales

Klaviyo is a cloud subscription billed monthly on active-profile tier per its calculator at klaviyo.com/pricing. AcelleMail is a one-time license you self-host on a VPS plus a sending service. The dollar values below assume Amazon SES at $0.10 per 1,000 emails for the AcelleMail rows. Specific Klaviyo tier prices change — consult the Klaviyo pricing calculator for current values at your profile count.

Small e-commerce — 1,000 active profiles, 4× sends/month

Klaviyo — Klaviyo Free or entry-tier paid Email plan Klaviyo Free covers "Up to 250 profiles · 500 emails/month"; 1,000 profiles requires a paid Email plan billed monthly per the active-profile calculator on klaviyo.com/pricing.
Recurring monthly subscription × 36 months — verify against the calculator at your profile count.
AcelleMail — AcelleMail Regular License + small VPS + Amazon SES $5/mo VPS + $0.40/mo SES (4,000 sends × $0.0001)
$80 license + $180 VPS + $14 SES = $268 total

At 1,000 profiles, AcelleMail one-time cost is ~$268 over 3 years. Tradeoff: AcelleMail does not include Klaviyo's pre-built e-commerce flows, predictive analytics, or first-party Shopify integration — those would be plugin work via the SDK.

Growing DTC brand — 10,000 active profiles, 80,000 sends/month

Klaviyo — Klaviyo Email plan at 10K active-profile tier Klaviyo Email plan billed monthly per the 10K active-profile tier on klaviyo.com/pricing. Email + SMS plan adds SMS credits for cart-abandonment SMS flows.
Recurring monthly subscription × 36 months — verify against current calculator pricing.
AcelleMail — AcelleMail Regular License + $10 VPS + Amazon SES $10/mo VPS + $8/mo SES (80,000 × $0.0001)
$80 license + $360 VPS + $288 SES = $722 total

At 10K profiles, AcelleMail self-hosted on SES converges to roughly $20/month after the license is amortized. The difference covers: predictive analytics, pre-built e-commerce flow templates, dedicated Shopify Plus integration. Teams whose stack is WordPress + WooCommerce often find the AcelleMail bundle a closer fit.

Agency / SaaS — 50 client lists, 50,000 aggregate profiles

Klaviyo — Klaviyo for Agencies (partner accounts) or 50 separate subscriptions Klaviyo for Agencies provides partner-tier discounts on individual client subscriptions. Aggregate cost varies by partner-tier discount and per-client active-profile count.
50 client subscriptions × partner-tier rate × 36 months.
AcelleMail — AcelleMail Extended License + $20 VPS + Amazon SES (multi-tenant on a single instance) $20/mo VPS + $5/mo SES (50,000 × $0.0001) — covers all 50 tenants on one install.
$199 license + $720 VPS + $180 SES = $1,099 total

AcelleMail Extended ships a multi-tenant SaaS layer (customer accounts, plans, 6 payment gateways, dunning) bundled. Klaviyo for Agencies provides partner-discounted access to individual Klaviyo accounts but does not bundle reseller-billing primitives.

Playbook de migración

Klaviyo → AcelleMail en siete pasos

La mayoría de los equipos hacen la transición en menos de una semana. La configuración técnica es media jornada; el paso que más tiempo lleva es reconstruir las automatizaciones de varios pasos y las plantillas.

  1. 1. Export from Klaviyo

    In the Klaviyo dashboard, export profiles as CSV from Audience → Profiles → Export. Per Klaviyo terms of service, "Customer shall have the ability to retrieve or export Customer Data out of the Services using the self-service tools Klaviyo makes available." For programmatic export, the Profiles API at GET /api/profiles/ returns paginated profiles with attributes and event history. Campaign HTML can be retrieved per-campaign via the Campaigns API. Export before cancellation — Klaviyo has no post-termination data retention obligation.
  2. 2. Get AcelleMail

    Buy the Regular License — $80 on CodeCanyon. Download the ZIP, upload to your server, run the web installer (5 minutes — sets DB, admin user, cron). PHP 8.1+, MySQL ≥ 5.7 or MariaDB ≥ 10.3, ~512 MB RAM minimum. The installation guide walks through cPanel, DigitalOcean, AWS, and Docker.
  3. 3. Configure your sending service

    In Sending Servers → Add, pick Amazon SES (recommended — cheapest), SendGrid, Mailgun, SparkPost, Postmark, Elastic Email, or any SMTP. AcelleMail handles SPF/DKIM record generation. Run the test-send to confirm. The 8 built-in drivers live in app/SendingServers/Drivers/Vendors/. SES at $0.10 per 1,000 emails is the typical recommendation for high-volume e-commerce traffic.
  4. 4. Import profiles + custom properties

    In Lists → Create List, recreate your Klaviyo lists with their property schema (Klaviyo profile properties map to AcelleMail subscriber custom fields one-to-one). Use Import → Upload CSV and map columns. For lists over 100K, use the chunked import or seed via the REST API. Klaviyo events history (purchases, browse, view) can be imported as date-stamped subscriber attributes for segmentation.
  5. 5. Recreate templates and flows

    For Templates, paste your Klaviyo HTML into AcelleMail's template editor. Substitution syntax differs: Klaviyo Templates use {{ first_name }} Django-style; AcelleMail uses {{ subscriber.first_name }} Twig-style. Subscriber-attribute access is equivalent. For Flows, rebuild logic in Automation → New Workflow using the visual builder. E-commerce-specific flows (cart abandonment, post-purchase) need to be wired to the WooCommerce / shop-platform event source.
  6. 6. Wire e-commerce events

    Klaviyo Flows trigger on purchase / browse / view events from the connected store. AcelleMail + WooCommerce: the official AcelleMail WordPress plugin fires order events that can trigger automation flows. Shopify customers staying on Shopify need a custom plugin (built via the AcelleMail SDK REGISTRY pattern + Shopify webhooks) to bridge the platforms — Shopify integration is not in AcelleMail core.
  7. 7. Test deliverability + cut over

    Send a test campaign to GlockApps or Mail-Tester (free). Aim for 9.5/10. Run the next live campaign from AcelleMail in parallel for one cycle, watch open/click rates against your prior baseline, then turn off Klaviyo. Plan the cancellation timing per Klaviyo terms — monthly billing requires 5 days prior notice; annual billing requires 30 days.
Encaje operativo

Cuándo el autoalojamiento no es la opción adecuada

El email marketing autoalojado es una contrapartida: menor coste y propiedad completa a cambio de responsabilidad operativa. Un SaaS gestionado puede ser la mejor opción para cualquiera de las situaciones de abajo.

  • Your store runs on Shopify Plus

    Klaviyo is the recommended email solution for Shopify Plus following Shopify's August 2022 strategic investment. Shopify-tier teams who rely on the deep first-party data pipeline (real-time order events, browse tracking, product feeds, predictive analytics trained on Shopify purchase data) get that integration depth out of the box. AcelleMail does not ship a Shopify integration in core — it would be plugin work via the SDK. Teams whose primary stack is Shopify often find Klaviyo a closer fit for that reason.

  • You rely on predictive analytics for segmentation

    Klaviyo includes predictive scores: Customer Lifetime Value, churn prediction, expected next-order date, and RFM analysis on paid Email tiers. AcelleMail does not include predictive scoring in core — comparable scoring would be plugin work or external machine-learning pipelines feeding subscriber attributes via the REST API. Teams whose segmentation strategy depends on these scores out of the box may prefer Klaviyo.

  • You don't want to operate any server infrastructure

    AcelleMail is a self-hosted PHP application — you provision a VPS, install PHP-FPM + a web server, point a domain, and maintain backups. Teams that prefer a fully managed cloud service with no servers to operate may pick Klaviyo and accept the recurring subscription cost. The tradeoff is between recurring SaaS spend and one-time license + ops responsibility.

  • You need bundled SMS + email + reviews + customer hub

    Klaviyo bundles SMS campaigns, product reviews (Klaviyo Reviews), and a self-service Customer Hub in one product. AcelleMail core is email-focused; SMS / reviews / customer-portal modules would be custom plugin work or external services. Teams whose primary need is multi-channel marketing in one product may find Klaviyo a closer fit; teams that want email-platform control with separate channels for SMS / reviews may prefer AcelleMail + dedicated providers.

    Situación: 5,000 active profiles, weekly newsletter (~25K sends/month), abandoned-cart automation, post-purchase flow.

    Coste de Klaviyo: Klaviyo Email plan at 5K active-profile tier billed monthly. Email + SMS plan if cart-abandonment SMS is in scope.

    Coste de AcelleMail: $80 once + $5/mo VPS + ~$2.50/mo SES (25K × $0.0001). Cart-abandonment automation wired through the official AcelleMail WooCommerce plugin's order hook.

  • Marketing agency — 50 e-commerce clients

    Situación: Email service for 50 small e-commerce clients (mix of WooCommerce + custom storefronts), average 1,000 profiles each, monthly newsletter + cart abandonment.

    Coste de Klaviyo: Klaviyo for Agencies partner-tier subscriptions for 50 separate client accounts; reseller-billing built externally.

    Coste de AcelleMail: $199 Extended License once + $40/mo VPS + ~$30/mo SES total across all clients on one install. Built-in SaaS layer: per-client login, plans, dunning, 6 payment gateways. WooCommerce sync via the AcelleMail plugin.

  • Indie newsletter — non-e-commerce

    Situación: 5,000 subscribers, weekly newsletter, no e-commerce events, no SMS.

    Coste de Klaviyo: Klaviyo Email plan at 5K active-profile tier billed monthly. Predictive analytics features may be unused for non-e-commerce audiences.

    Coste de AcelleMail: $80 license + $5/mo VPS + ~$2/mo SES (20K × $0.0001). License recovers ~12-24 months of equivalent paid SaaS subscription if previously paying for a hosted email platform.

  • Coste de AcelleMail: $199 Extended License once + $40/mo VPS + ~$30/mo SES total across all clients on one install. Built-in SaaS layer: per-client login, plans, dunning, 6 payment gateways. WooCommerce sync via the AcelleMail plugin.

Indie newsletter — non-e-commerce

  • Situación: 5,000 subscribers, weekly newsletter, no e-commerce events, no SMS.
  • Coste de Klaviyo: Klaviyo Email plan at 5K active-profile tier billed monthly. Predictive analytics features may be unused for non-e-commerce audiences.
  • Coste de AcelleMail: $80 license + $5/mo VPS + ~$2/mo SES (20K × $0.0001). License recovers ~12-24 months of equivalent paid SaaS subscription if previously paying for a hosted email platform.

Contraposicionamiento honesto — objeciones habituales para cambiar

Cuatro objeciones que sopesa todo operador antes de migrar desde Klaviyo o desde cualquier SaaS. Respondidas sin maquillaje: son contrapartidas reales, y la elección correcta depende de su equipo.

1. «Cambiar cuesta más de lo que ahorra».

Evaluación honesta: con listas por debajo de ~500 contactos, el nivel gratuito o de entrada de Klaviyo puede ser más barato que ejecutar un VPS de $5–10/mes más la licencia de AcelleMail, incluso sin contar el tiempo del operador. El punto de equilibrio suele situarse entre 1.000 y 5.000 contactos. Haga sus propias cuentas con la calculadora de coste antes de decidir.

2. «La entregabilidad en autoalojamiento se va a hundir».

Cierto si ejecuta un MTA autogestionado sin warm-up. NO es cierto cuando AcelleMail reenvía a través de un servicio de envío gestionado (Amazon SES, SendGrid, Mailgun, Postmark): esos proveedores mantienen la reputación de IP; AcelleMail solo orquesta campañas y seguimiento. Alcanzar la paridad de colocación en bandeja de entrada con Klaviyo es la norma, no la excepción, con este montaje.

3. «Mi equipo no tiene tiempo para aprender otra herramienta».

Preocupación legítima. La UI de AcelleMail refleja los patrones habituales (constructor de campañas, listas de audiencia, flujos de automatización), así que la mayoría de los usuarios de Klaviyo son productivos desde el primer día. El verdadero sumidero de tiempo es reconstruir las automatizaciones de varios pasos y las bibliotecas de plantillas: planifique de 1 a 5 días según la complejidad, no semanas.

4. «¿Y si AcelleMail deja de mantenerse?»

El autoalojamiento le da la vuelta al riesgo: usted es dueño de una copia perpetua del código fuente. Ningún cambio de precio, deprecación o adquisición del proveedor puede quitarle la plataforma. Si las actualizaciones se detienen, su instalación existente sigue funcionando. Compárelo con el SaaS, donde las decisiones del proveedor sobre precio, funciones o cierres son unilaterales.

Preguntas frecuentes

Preguntas habituales

¿Puedo migrar de Klaviyo a AcelleMail sin perder los datos de los suscriptores?
Sí. Klaviyo exporta perfiles como CSV desde el dashboard; la Profiles API en GET /api/profiles/ devuelve JSON paginado para una exportación programática completa. Según los términos de Klaviyo, «el Cliente tendrá la capacidad de recuperar o exportar los Datos del Cliente fuera de los Servicios usando las herramientas de autoservicio que Klaviyo pone a disposición.» La importación de AcelleMail acepta CSV con mapeo de campos personalizados y admite XLSX o un seed directo de BD para listas muy grandes. Planifique medio día para una lista de menos de 5.000 perfiles; entre 2 y 3 días para tiendas con lógica de flujos extensa por reconstruir. Exporte antes de cancelar.
¿AcelleMail se integra con Shopify como hace Klaviyo?
AcelleMail no entrega una integración con Shopify en el core; sería trabajo de plugin vía el SDK de AcelleMail, usando el patrón REGISTRY + webhooks de Shopify. La integración de ecommerce de primera línea de AcelleMail es el plugin oficial de WordPress / WooCommerce. Klaviyo es la solución de email recomendada por Shopify para Shopify Plus tras la inversión estratégica de agosto de 2022. Los equipos cuyo stack principal es Shopify Plus suelen encontrar Klaviyo un encaje más cercano por esa razón; los equipos que ejecutan WordPress + WooCommerce normalmente encuentran que la integración nativa de AcelleMail es suficiente.
¿Cómo se compara la automatización de AcelleMail con los Flows de Klaviyo?
AcelleMail Automation2 entrega un constructor visual de flujos con nodos trigger / wait / condition / send / tag-update / segment-move. Los Klaviyo Flows incluyen un constructor de flujos visual similar con triggers específicos de ecommerce y plantillas prediseñadas (abandono de carrito, post-compra, abandono de navegación). AcelleMail puede construir flujos comparables conectándolos manualmente a eventos de WooCommerce. La principal carencia: las plantillas prediseñadas de ecommerce de Klaviyo y la ramificación impulsada por scores predictivos vienen incluidas; los flujos de AcelleMail replicarían la lógica sin el scoring predictivo.
¿Por qué AcelleMail cobra $80 si Klaviyo ofrece un nivel Free?
La Licencia Regular de AcelleMail ($80 de pago único) es una licencia comercial que incluye actualizaciones de versiones point + menores de por vida, 6 meses de soporte y código fuente PHP completo, sin tarifas recurrentes por email o por perfil. El nivel Free de Klaviyo cubre, según su página de precios, «Hasta 250 perfiles · 500 emails/mes · 150 créditos mensuales de mensajes móviles». Por encima de 250 perfiles, los planes de pago Email o Email + SMS facturan mensualmente según el nivel de perfiles activos. Los $80 cubren un paquete distinto: automatización visual, SDK de plugins, 8 drivers de envío, UI multilingüe y la capa SaaS multi-tenant ($199 Extendida).
¿AcelleMail incluye analíticas predictivas como Klaviyo?
No. El Valor de Vida del Cliente predictivo, la predicción de churn, la fecha esperada del próximo pedido y el análisis RFM son funciones de Klaviyo construidas alrededor de su modelo de datos de ecommerce. AcelleMail no incluye scoring predictivo en el core. Un scoring comparable sería trabajo de plugin usando el SDK de AcelleMail o un pipeline de ML externo que alimente los atributos del suscriptor vía la REST API. Los equipos cuya estrategia de segmentación depende de scores predictivos de fábrica suelen preferir Klaviyo por esa razón.
¿Puedo ejecutar varias cuentas de cliente bajo una sola instalación de AcelleMail?
Sí — eso es la Licencia Extendida de AcelleMail ($199). Incluye una capa multi-tenant: cuentas de cliente, planes de suscripción, 6 pasarelas de pago (Stripe, PayPal, Braintree, Razorpay, Paystack, Offline), upgrades prorrateados, dunning y marca blanca. Klaviyo for Agencies es un programa de partners para suscripciones individuales por cliente; la facturación de revendedor se construye fuera de Klaviyo. Vea la página Para agencias para la arquitectura.
¿Qué stack necesita AcelleMail frente a Klaviyo?
AcelleMail: PHP 8.1+, MySQL ≥ 5.7 o MariaDB ≥ 10.3, ~512 MB de RAM mínimo, 1 GB recomendado para listas de hasta ~50K. Corre bajo PHP-FPM tras nginx o Apache. Klaviyo es un servicio en la nube gestionado por Klaviyo, sin stack que alojar del lado del cliente. La superficie del lado del cliente es la REST API en developers.klaviyo.com (Private API key, OAuth o Public key) según el resumen de la API.
¿AcelleMail tiene un SDK de plugins?
Sí. AcelleMail entrega un sistema de Hooks de cuatro patrones (REGISTRY, EVENT, FILTER, BEHAVIOR) — los plugins viven bajo storage/app/plugins/ y pueden registrar drivers de envío, pasarelas de pago, paneles de UI y hooks del ciclo de vida. Vea la documentación del SDK de plugins para los cuatro patrones y los ejemplos trabajados (Postal MTA, pasarela Paddle, plugin de IA). La extensión de Klaviyo es vía la REST API pública + webhooks basados en topics; no hay runtime de plugins en proceso.
¿Dónde viven mis datos con AcelleMail frente a Klaviyo?
Los datos de AcelleMail viven en la base de datos del VPS que aprovisionó. Usted elige la residencia de los datos eligiendo la región del VPS. Klaviyo lo opera Klaviyo (con sede en Boston) sobre la infraestructura cloud de Klaviyo según sus términos de servicio; «Klaviyo no tendrá obligación de conservar ningún Dato del Cliente tras la terminación o expiración de este Acuerdo.» Planifique las exportaciones antes de cancelar. La retención de datos en AcelleMail la decide usted.
