These Are Different Tools

Let's be clear upfront: SMTP2GO and Sequenzy solve different problems.

• SMTP2GO is an SMTP relay service. They focus on reliable email delivery through SMTP and API. Plug them in, send emails, they handle deliverability.

• Sequenzy is a full email platform for SaaS. It combines transactional emails, marketing campaigns, and automation in one place.

Comparing them directly is a bit like comparing a delivery truck to a full logistics company. Both move packages, but they're optimized for different needs.

When should you choose Sequenzy?

1. You Need Marketing Automation

SMTP2GO is email relay—SMTP/API for sending, no marketing features. If you need welcome sequences, drip campaigns, triggered automations, or audience segmentation, SMTP2GO doesn't do this. Sequenzy has a full automation builder.

2. You Want AI-Generated Content

Describe what you want ("a 5-email onboarding sequence for a project management SaaS") and our AI generates the entire sequence. SMTP2GO is pure infrastructure—no content generation, no email writing assistance.

3. You Need Subscriber Management

SMTP2GO doesn't have subscriber lists, segments, or contact profiles. You manage all that in your own application and call their SMTP/API when you want to send. Sequenzy gives you a full subscriber management system with tags, segments, and custom fields.

4. You Need Stripe Integration

Sequenzy connects directly to Stripe via our native integration—syncing customer data, subscription status, MRR, and churn signals. SMTP2GO doesn't integrate with billing systems.

5. You Want Visual Campaign Builder

If you're building marketing campaigns with a drag-and-drop editor, Sequenzy has a visual email builder. SMTP2GO is relay-only—you bring your own HTML or use another tool to create emails.

When should you stick with SMTP2GO?

1. You Only Need SMTP Relay

If your use case is purely sending emails via SMTP and you're handling everything else (lists, templates, automation) in your own application or another tool, SMTP2GO is purpose-built for this.

2. Phone Support Is Important

SMTP2GO offers phone support on all paid plans. If you need to call someone when things break, this is a real advantage. We don't offer phone support.

3. You Need a Dedicated IP

SMTP2GO's Professional plan ($75/mo) includes a dedicated IP for reputation control. We don't offer dedicated IPs. Use our blacklist checker to monitor your domain reputation.

4. You Need Global Server Distribution

SMTP2GO has servers in six locations (Chicago, London, Amsterdam, Singapore, Sydney, New Zealand) plus data centers in Amsterdam and New York. For latency-sensitive delivery worldwide, this can matter.

5. You're Cost-Sensitive for Pure SMTP

SMTP2GO's Starter plan is $10/month for 10,000 emails. If you only need SMTP relay and don't need marketing, that's cheaper than our $49/mo for similar volume. Check our pricing page for full details.

Honest Limitations of Sequenzy

• No phone support: We offer chat and email, not phone calls.

• No dedicated IPs: We don't offer dedicated IP addresses for reputation control.

• No data center choice: We don't let you choose specific data center locations.

• More expensive for pure SMTP: $49/mo vs SMTP2GO's $10/mo at 10k emails if you only need relay.

• No landing pages: We don't have a landing page builder.

Honest Limitations of SMTP2GO

• No marketing automation: No sequences, no drip campaigns, no triggered emails based on segments. We offer AI-powered sequences.

• No subscriber management: No lists, segments, or profiles. SMTP/API-only.

• No campaign builder: No visual editor for marketing campaigns. Check our email editor.

• No AI content generation: You write or source all email content yourself.

• No billing integration: No Stripe sync, no MRR tracking, no SaaS-specific features.

• Gets expensive at high volume: Professional ($75/mo for 100k) and Premier (custom) pricing can add up. Some plans cost $500+/month.

A Note on Architecture

SMTP2GO and Sequenzy can coexist:

• Use SMTP2GO as a relay layer for delivery infrastructure
• Use Sequenzy for marketing automation and campaign management

But this adds complexity. Sequenzy handles transactional email delivery directly, so unless you have specific needs (dedicated IP, global server distribution, phone support), you probably don't need both.
