Frequently Asked Questions

What’s the difference between marketing and transactional email?

Marketing email is promotional or editorial and usually requires consent. Transactional email is triggered by a user action (e.g., password reset) and contains essential information.

Do I need an SMTP service if I use an email marketing platform?

Many platforms include SMTP/API sending, but teams often combine a marketing suite with a dedicated SMTP service for transactional messages or to improve inbox placement and scalability.

How long does it take to see results from email marketing?

You can see early wins within days (welcome opens and clicks), while revenue and retention gains compound over weeks as you refine segments, content, and cadence.

What deliverability mistakes should I avoid?

Avoid bought lists, sudden volume spikes, misleading subjects, image‑only emails, and ignoring bounces/complaints. Authenticate and warm gradually.

Can I migrate from another ESP?

Yes. Bring your lists (with consent), suppression files, templates, and DNS records. We’ll guide authentication, warmup, and list hygiene during onboarding.
