A/B Testing – Included in Every Plan
Stop guessing.
Start converting.
The only email tool that lets you split test everything – sender name, subject line, content, offers, CTAs, and layouts. All in one campaign.


Built by the team behind
WordPress’s biggest platforms.
WHY A/B TESTING
Conversion-first Email Marketing
SureContact is an email tool where the default is to test, learn, and improve
– instead of “blast and hope.”
Split test sender names, from addresses, body copy, offers, CTAs, layouts, and send times – all inside one campaign builder
Define your winning metric – opens, clicks, or revenue. SureContact monitors the live results and automatically sends the winner to the rest of your list.
Each test refines your understanding of your audience. Over time, your list becomes a perpetual optimization engine – not just a broadcast channel.
Write two subjects.
Let data pick the winner.
Test curiosity vs. clarity, urgency vs. personalization, emojis vs. plain text. Find the subject line formula that makes your specific audience open.
-
Test up to 5 subject line variants per campaign
-
See real-time open rates as results roll in
-
Winner auto-sends when your test window closes
-
Results saved to your audience insights

Does your name matter
more than your brand?
Test “Alex from SureShop” against “Team SureShop.” Personal sender names consistently outperform brand names — but the best answer is your own data.
-
Test display name, from address, and reply-to
-
Isolate the sender variable without changing content
-
Build audience trust signals over time
-
Segment results by list or audience tag

Long-form vs punchy.
Find what converts.
Test entirely different email bodies — storytelling vs. bullet points, image-heavy vs. text-first. SureContact lets you test the entire message, not just surface details.
-
Full email body A/B — not just subject or preview text
-
Test layouts: single column vs. multi-column
-
Image-first vs. text-first approaches
-
Compare click-through rates per variant

Small wording changes.
Big revenue differences.
“Buy now” vs. “Claim your discount” vs. “See what’s new.” Test your CTA copy, button color, offer framing, and discount structure — let revenue be the judge.
-
Test CTA button text and placement
-
Compare offer types: % off vs. free shipping vs. bonus
-
Track revenue attribution per variant
-
Works with SureCart for direct revenue data

When you send matters
as much as what you send.
Test whether your audience engages more on Tuesday morning or Thursday evening. Schedule by timezone and let the data set your optimal send window.
-
Test across different days of the week
-
Compare morning, afternoon, and evening slots
-
Timezone-aware scheduling built in
-
Optimal time learns with each campaign

WHAT OUR USERS ARE SAYING
“SureContact is on another level. I love that the heavy lifting happens outside WordPress, and the connector syncing multiple sites into one dashboard is exactly what I needed. I’ve finally ditched MailerLite.”

Dariusz Chrobak
SureContact User
SureContact’s connector-based implementation is way better than MailerPress. No comparison.

Luis Apple
SureContact User
You guys are the GOAT! The speed of implementation is unchallenged to any other software provider l’ve ever used. Simply Amazing! Thanks, I’ll get started with setting everything up using Mailersend now.

Greger Hillman

I expected SureContact to be a nice-to-have. 67 minutes later, I loved it. It feels like OttoKit’s answer to email.

Kaneisha Grayson
Demo Queen
Incredibly fast and responsive support. List-Unsubscribe and List-Unsubscribe-Post headers were implemented immediately, and everything worked perfectly in testing.

Hervé Lancelin
