Built Different

Six reasons B2B teams outgrow Klaviyo

Where EVOX takes a different approach because service teams have different problems than online stores.

Your sender reputation belongs to you

Klaviyo routes everything through its own shared pool. EVOX connects to AWS SES, Gmail, Outlook, or Resend with your credentials. When you build deliverability, that history stays with your domain.

Content reviewed before it leaves your account

EVOX runs spam pattern analysis before every send with a deliverability score and specific fix suggestions. Most B2B teams discover their subject lines trigger filters only after open rates drop. EVOX catches it first.

Your CRM feeds your campaigns directly

EVOX syncs natively with LIO. New leads appear in campaign segments automatically. Klaviyo pulls from Shopify stores. EVOX pulls from the contacts your sales team is actually working.

Know the outcome before you commit the send

EVOX predicts open rate, click rate, and revenue impact before launch. Klaviyo shows attribution after a campaign. EVOX gives you the baseline before you spend.

Variants that test strategy, not punctuation

The Auto A/B Champion Generator writes variants with genuinely different angles, then monitors performance and picks the winner on statistical confidence. Better test results without the copywriting hours.

One campaign signal moves your entire operation

When a contact converts through EVOX, LIO updates the CRM, SIGI triggers a contract, TARO creates a task, and INZO sends an invoice. Klaviyo is a standalone channel. EVOX is one part of a system that talks to itself.

Real Results

Why B2B teams are making the switch

From consultancies that outgrew Klaviyo to SaaS companies that needed campaigns connected to their pipeline. Real teams, real results.

Klaviyo assumed we were selling products. We are not. The LIO sync alone saved us three hours a week. Contacts are always current without anyone touching an export file.

The spam check caught two phrases triggering corporate email filters on our very first campaign. We fixed them before sending. Best open rate in six months.

Klaviyo's infrastructure is a black box. With EVOX we run through our own AWS SES account. Deliverability is measurably better and we can actually investigate issues.

Answers that matter

Five things B2B teams ask before switching from Klaviyo to EVOX

Yes. EVOX is built for B2B and service teams. Klaviyo's strongest features like product recommendations and CLV scoring require e-commerce data. If you do not have a product catalogue, those capabilities go unused.

Your email tool should see beyond the inbox.

EVOX connects campaigns to your CRM, contracts, invoicing, and tasks. Nine AI capabilities, your own sending infrastructure, and results predicted before you hit send.
