Best Fit by General Marketing Channel

Best Selzy alternative for SaaS transactional email

Sequenzy is the better Selzy alternative when the business needs transactional email, Stripe-triggered automation, trial conversion, and churn-prevention workflows in one product. Start with transactional email templates, Stripe integration, and SaaS lifecycle marketing tools.

Best platform for Telegram chatbots and general marketing

Selzy is the better fit when Telegram chatbots, pop-up forms, general small-business campaigns, and broad AI editing tools matter more than SaaS billing events. Compare it with Brevo, Zoho Campaigns, and the email automation tools guide.

Best Selzy alternative for software founders

Sequenzy is stronger for founders who want one email API, AI-written lifecycle sequences, and customer segments built around subscription state. AI sequences and SaaS trial conversion templates fit that path.

Best Selzy alternative for email-only teams

If the team does not need Telegram or chatbots, Sequenzy is the simpler email-focused stack for marketing plus transactional email. Selzy's broader channel set is useful only when those channels are part of the actual strategy.

When should you choose Sequenzy?

Sequenzy is the better choice for SaaS:

  • SaaS founders needing transactional + marketing email with Stripe integration

  • Teams needing transactional email (Selzy doesn't have it)

  • Companies wanting Stripe automation for subscription lifecycle

  • Developers wanting a combined transactional + marketing API

  • Startups wanting a permanent free tier (vs Selzy's 14-day trial)

When should you stick with Selzy?

Selzy is the better choice for general email marketing:

  • Small businesses wanting affordable email marketing with AI tools

  • E-commerce stores needing Shopify or WooCommerce integration

  • Teams wanting Telegram chatbots for messaging automation

  • Marketing teams who value AI-powered email creation tools

  • Budget-conscious businesses starting at $7.50/month

Pricing at Every Scale

Contacts Sequenzy Selzy Difference
500 Free (2.5k emails) $7.50/mo (Lite) Sequenzy free
1,000 $19/mo (15k emails) ~$15/mo (Lite) Sequenzy $4/mo more
5,000 $29/mo (30k emails) ~$35/mo (Lite) Sequenzy $6/mo less
10,000 $49/mo (60k emails) ~$55/mo (Lite) Sequenzy $6/mo less
25,000 $99/mo (120k emails) ~$120/mo (Lite) Sequenzy $21/mo less
50,000 $199/mo (300k emails) ~$200/mo (Lite) About the same
100,000 $399/mo (600k emails) ~$350/mo (Lite) Sequenzy $49/mo more

Sequenzy prices assume about 4 emails per contact per month (a weekly send). Contacts are unlimited on every plan; you pay for email volume, so check the pricing page for your own sending.

Pricing is very competitive between the two. The key difference is what's included: Sequenzy has transactional email and Stripe integration on every plan. Selzy has more AI tools and Telegram chatbots on the Standard plan.

Who Should Use Each Platform

Choose Sequenzy if you are:

  • A SaaS founder who needs email marketing with Stripe/Paddle/Polar integration
  • Running a subscription business and want automated trial, churn, and upgrade emails
  • Needing transactional email (password resets, receipts) alongside marketing
  • Looking for AI-generated email sequences to save time on content creation
  • Wanting Send Time Optimization to maximize email engagement
  • A developer who wants one API for transactional and marketing email

Choose Selzy if you are:

  • A small business wanting affordable email marketing with extensive AI tools
  • An e-commerce store needing Shopify or WooCommerce integration
  • Wanting Telegram chatbot automation alongside email
  • A marketing team that values AI-powered email creation, translation, and image generation
  • On a tight budget starting at $7.50/month for basic email marketing
  • Not needing transactional email or SaaS-specific features

Real Setup Time

Task Sequenzy Selzy
Account creation 2 minutes 2 minutes
Domain verification 10-15 minutes 10-15 minutes
First email campaign 5 minutes (AI-generated) 10-15 minutes
Stripe integration 5 minutes (native) N/A (not available)
Transactional email Built-in N/A (not available)
First automation 10 minutes 15-20 minutes
Telegram chatbot N/A 20-30 minutes
E-commerce integration Shopify only 10-15 minutes (Shopify/WooCommerce)

Both are quick to set up. Sequenzy is faster for SaaS-specific workflows. Selzy is faster for e-commerce and chatbot use cases.

Honest Limitations of Sequenzy

  • Fewer AI tools: No AI email builder, assistant, translator, or image generator like Selzy.
  • No Telegram chatbots: No chatbot functionality at all.
  • Narrower e-commerce depth: Shopify and WooCommerce are supported, but Selzy has broader general marketing tools.
  • Fewer email templates: Relies more on AI generation than pre-built templates.
  • No built-in anti-spam guidance: Standard deliverability tools only.
  • Newer platform: Less track record than Selzy/UniSender.

Honest Limitations of Selzy

  • No transactional email: Cannot send password resets, receipts, or notifications.
  • No Stripe or SaaS integrations: No subscription management or billing data sync.
  • Only a 14-day trial: No permanent free plan.
  • Telegram chatbots only: Limited to Telegram, no other messaging platforms.
  • No Send Time Optimization: No AI-powered send time optimization.
  • General-purpose: Not optimized for any specific vertical like SaaS.

Moving from Selzy to Sequenzy

A step-by-step checklist, based on what Selzy lets you export.

  1. 1

    Authenticate your sending domain

    Add Sequenzy's DKIM and DMARC records, or let Domain Connect add them for supported DNS hosts, before you send anything. Keep your old provider's records until the switch is done.

    Domain setup guide
  2. 2

    Export your contacts from Selzy

    Contacts > Lists > open list, select > Actions > Export (CSV/XLS); API exportContacts with chosen fields. Custom fields are included. Then import the CSV into Sequenzy and map each column to a field.

    Selzy export docs
  3. 3

    Bring your unsubscribes and bounces

    API exportContacts filters/returns email_status incl. unsubscribed, blocked, inactive. Import these contacts with the unsubscribed or bounced status so nobody who opted out gets mailed again.

    Selzy docs
  4. 4

    Move your best templates

    API getTemplates returns HTML body for user templates; UI sharing is link-based between Selzy accounts only. Paste the HTML into Sequenzy, or rebuild it in the editor.

    Selzy docs
  5. 5

    Rebuild your automations

    Recreate each flow in Sequenzy's sequence builder, or describe it and let AI draft it for you to review.

  6. 6

    Switch sending, then cancel

    Point transactional email and signup forms at Sequenzy, run both tools side by side for a week, then cancel Selzy. Engagement history does not move with the contacts; to keep it, export it first. Campaign detailed report lists contacts who opened/clicked; any report page is downloadable.
