List growth
Email list growth and capture that protects deliverability
Signup forms convert around 2% by default, and most of that number is set by form type and field count. We build click-triggered and exit-intent popups, double opt-in capture, and cart-recovery sign-up moments that grow a clean, engaged list.
List growth is about quality as much as size. The baseline signup-form conversion rate is about 2%, 1.95% at BDOW and 2.1% at Omnisend, and the format you choose moves it far more than the offer. A confirmed, engaged list earns more per send than a larger one full of addresses that never open, so we capture for engagement, not just for volume.
What signup conversion rate is realistic at 2%?
Two percent is the all-forms average, and the bands tell you where you stand: under 1.5% is poor, 1.5% to 3% is average, 3% to 8% is good, and above 8% is exceptional. We treat the 2% baseline as a floor. Most programs sit there because they run one generic form, when format, timing and field count can push capture well into the good band.
Which popup type converts best above 4%?
Click-triggered two-step popups, at 4.1% in OptinMonster's data, followed by exit-intent at 3.8%, fullscreen at 3.4%, modal at 2.95% and sticky bars at 2.3%. Field count moves the number again: forms with about 3 fields convert near 25%, while 6 or more fall toward 15%. We match the format to the page, ask for the minimum, and add fields only when a later segment needs them.
Why does double opt-in lift opens 72.2%?
Because confirmation filters the list to people who genuinely want it. Mailchimp's study found double opt-in beating single opt-in by 72.2% on opens and 114% on clicks. The extra click removes typos, bots and throwaway addresses before they land on your list, which keeps bounces and spam complaints low. That directly protects placement, so our email deliverability work and capture work pull the same direction.
How does a 70.22% cart abandonment rate become capture?
Baymard puts average cart abandonment at 70.22%, so most checkouts are abandoned. Capturing the email before or at the cart step turns those lost sessions into contacts you can recover. The address feeds an abandoned-cart sequence, which is among the highest-earning flows we build. Capture and flow work as a pair, set up in lifecycle email automation.
How does list growth fit the wider program?
Capture feeds the flows, double opt-in protects placement, and segmentation puts the new contacts to work. We build the forms, wire the confirmation, and connect each source to the right sequence. See which capture and flow work each plan covers on pricing.

FAQ
List growth questions
What signup conversion rate should I expect?
About 2% across all forms is the baseline, with BDOW at 1.95% and Omnisend near 2.1%. Under 1.5% is poor, 1.5% to 3% is average, 3% to 8% is good, and above 8% is exceptional. Form type and field count move that number a lot, so we treat 2% as a floor to beat rather than a target to settle for.
Which popup type converts best?
Click-triggered two-step popups lead at 4.1%, with exit-intent at 3.8%, fullscreen at 3.4%, modal at 2.95% and sticky bars at 2.3%, per OptinMonster. Field count matters too: forms with about 3 fields convert near 25%, while 6 or more drop toward 15%. We pick the format and trim the fields to the page and the audience.
Is double opt-in worth the extra step?
Usually yes. Mailchimp measured double opt-in against single opt-in and found 72.2% more opens and 114% more clicks. The confirmation step removes typos and bots before they reach your list, which keeps bounces and spam complaints down. A smaller list of confirmed addresses protects deliverability and earns more per send than a bigger unconfirmed one.
Can an abandoned cart become a capture moment?
Yes, and it should. Baymard puts the average cart abandonment rate at 70.22%, so most checkouts never finish. Asking for an email before checkout, or capturing it at the cart step, turns a lost sale into a contact you can recover through an abandoned-cart flow. The capture and the flow work together, one feeds the other.
