  • Transactional (sep.)
    ~$15/mo
    For 20k transactional sends — billed separately from marketing

Plans scale by sends/month + features; transactional is a separate add-on past the entry tier.

Sneaky pricing cliff: Brevo’s headline price covers email volume, but you’ll pay extra for SMS, advanced automation, multi-user team seats, and dedicated IPs. For a WordPress site that just needs reliable transactional + form notifications, our flat $19/mo Pro tier covers what Brevo prices as a $40–$60/mo combination once you add the bits you actually use.

Apples and oranges, mostly.

Brevo is competing with HubSpot, Mailchimp, ActiveCampaign, and Klaviyo. Marketing automation + broadcast + CRM, sold by ARR-targeting AEs. If you have a marketing team and a 50k-name list, they’re a sensible pick.

SecureSMTP is competing with WP Mail SMTP + your bring-your-own-SMTP provider, and with Postmark for WordPress-shaped use cases. We’re a deliverability infrastructure tool, not a marketing platform. If you don’t need automation flows or a CRM, install us and stop paying for features your team won’t touch.

Common questions

Can I use Brevo for marketing and SecureSMTP for transactional?

Yes, and that’s a sensible architecture once you actually need marketing automation. Two separate concerns, two specialised providers. Brevo for newsletters + flows, SecureSMTP for wp_mail() + forms + transactional.

Will SecureSMTP ever add marketing automation?

No. We stay focused on deliverability infrastructure. If we add anything, it’s deeper analytics, more integrations, and better DKIM tooling — not flows and segmentation.

What about Brevo’s SMS capability?

That’s a great feature if you need SMS. We don’t support it. If SMS is on your roadmap, Brevo or Twilio (depending on volume) are better picks.

Does the SecureSMTP plugin conflict with Brevo’s WordPress plugin?

Yes — both hook into pre_wp_mail. Pick one for the wp_mail relay layer. You can still use Brevo’s plugin for marketing campaign sync and SecureSMTP for the transactional relay if you want — disable Brevo’s SMTP routing in their plugin settings.

Is SecureSMTP cheaper at scale?

For pure transactional + form-notification volume on WordPress: yes, by a large margin. For 100k-name newsletter campaigns: Brevo is purpose-built for that and would be the right pick.

Stop paying for marketing automation you don’t use.

If transactional + form notifications are all you need, you don’t need a $60/mo marketing suite. Install us free. Decide in 15 minutes.
