What is Sendster?
Sendster is a web-based email marketing and automation platform that combines traditional SMTP-based sending with an integrated AI content assistant to help users build campaigns faster. The product supports sending through Gmail/G Suite, Amazon SES, SendGrid, PowerMTA or any custom SMTP, and exposes campaign creation, list management, SMTP pooling, and delivery tracking in a single interface. Key features include an in-built AI writer for subject lines and message copy, a drag-and-drop or template-based email editor with HTML and plain-text support, scheduling with cron integration, attachments and unsubscribe handling, and multi-user / multi-site installation options for agencies or developers. Sendster is aimed at small-to-medium businesses, marketers, agencies, and developers who want self-hosted or installable email software with flexible SMTP routing and AI-assisted content creation for higher productivity and deliverability.
Sendster pricing
Pricing model: Paid
The website presents tiered paid plans (examples shown in third-party reviews): a lower ‘Elite’ plan, a mid ‘Pro’ plan, and a higher ‘Pro Max’ plan with increasing site installs and subscriber allowances; pricing examples reported elsewhere list Elite at about $17/month or $67/year (5,000 subscriber mention), Pro at about $27/month or $97/year (unlimited subscribers across 5 sites), and Pro Max at about $34/month or $127/year (installation on up to 30 sites). The product relies on external SMTP providers for actual sending so sending cost depends on the SMTP used (for example Amazon SES fees apply). The website emphasizes AI features and unrestricted sending through user-configured SMTPs; a members/login area indicates paid-account access, but the site does not prominently advertise a free sending tier or free plan limits on the public pages.

Frequently asked questions about Sendster
How does Sendster send emails — do I need a third-party SMTP?
Sendster uses the SMTP model and requires you to configure an SMTP provider (Gmail/G Suite, Amazon SES, SendGrid, PowerMTA or any SMTP) for actual delivery; the platform handles campaign composition, scheduling, SMTP pooling and dispatch, but sending costs and deliverability depend on the SMTP service you connect.
Does Sendster include an AI email writer and what can it generate?
Yes — Sendster includes an in-built AI writer that can generate subject lines, headlines, call-to-actions and full email copy; the AI can be used during campaign creation to auto-generate or suggest subjects and body text which you can edit before sending.
Can I schedule campaigns to send automatically?
Yes — Sendster supports scheduling campaigns, but scheduled sends require adding a cron job on your hosting (the site provides a script to copy into cPanel or server cron) so scheduling is available but needs a one-time server setup by the user.
Is Sendster hosted for me or do I self-install?
Sendster is offered as an installable/web-based package with a members area and multi-site installation options — this means you typically install or deploy the application (or use provided member resources) rather than relying on a fully managed sending infrastructure from Sendster itself.
How does Sendster handle deliverability and reputation?
Deliverability is managed through the SMTP provider you configure; Sendster provides features like multiple SMTP selection and pooling to spread load, but DKIM, SPF, IP warming and reputation management must be configured and monitored by the user or their SMTP provider for optimal results.
Can I upload attachments and use plain-text emails?
Yes — the campaign editor allows adding attachments and provides options for HTML templates or plain-text message bodies so recipients with limited HTML support can still receive properly formatted emails.
Does Sendster support multiple users or team accounts?
Yes — Sendster includes multi-user capabilities and a members area, enabling teams or agencies to manage campaigns, lists, and SMTPs across different users or sites within the installation.
What analytics and reporting are available after sending?
Sendster provides live campaign statistics such as total mails, delivered, pending and seen counts in the broadcast/campaign view, but it focuses on essential delivery metrics rather than deep behavioral analytics offered by some enterprise platforms.
Are there template or design tools included?
Yes — Sendster includes pre-designed templates and a template editor that lets you pick a template, edit HTML, or start from blank; templates can be saved for reuse across campaigns.
What are the limitations around subscriber lists and sites per plan?
The website and third-party reviews indicate plan-level limits such as a smaller Elite plan with a 5,000-subscriber mention and higher tiers offering unlimited subscribers across a limited number of sites (for example 5 sites or up to 30 sites on higher tiers), but exact limits and features depend on the specific paid plan you choose.
