Default Subscribe Page Not Collecting Email Addresses

Hi there. We’ve just started working with a client who has a highly seasonal business, so for several months of the year reverts their Klaviyo account to a free plan, until they need to start emailing profiles (likely to be August).

They’re getting traffic to their website all year round so we’re trying to capture users who might want to sign up out of season, but as the account is still on the free plan, and they’re over the 250 free profiles, we can’t launch a popup or embed form until the account goes paid. We’re therefore trying to use the default subscribe page, but any time we add test submissions, they don’t enter the database. 

Can anyone please advise? From what I can see from Klaviyo’s billing information, it’s possible to capture additional profiles while on a free plan, but I’m wondering if this is the blocker? 

We’ve tested from various platforms, IP addresses, email addresses etc etc. Any suggestions very welcome please. Thanks!

Hey ​@jess901 

when someone submits the subscribe page, Klaviyo tries to add them as a profile and, if the list is set to double opt-in, immediately sends a confirmation email. Once you're over the 250-profile limit on a free plan, Klaviyo blocks all sending, which means that confirmation email never goes out., The person clicks submit, sees the "check your email" message, and then nothing. ,They don't confirm, so they don't land in the list. That's probably why your test submissions look like they're disappearing.

so If it's double, switch it to single optin under list settings temporarily and re-test. If submissions start coming through, that confirms the sending block is the issue. ,Second, check whether the account is actually over that 250 active profile threshold right now, not just at the limit, because Klaviyo counts all active profiles in the account, not just subscribers to a specific list.

One workaround is suppressing all the existing profiles who don't need to receive anything during the off-season, which brings the active count back down and frees up room for new sign-ups to come in., You'd want to identify the profiles you're not actively sending to and bulk-suppress them so they don't count against the limit.

Worth confirming with your client whether they'd rather temporarily upgrade to a paid plan just for the capture period, or go the suppression route. i believe The paid plan costs less than losing a season of sign-ups.

I hope this helps and thank you for sharing your question here in the community.

Cheers,

Arpit.

Thanks so much, Arpit. Double opt-in was already removed and we were testing with our own email addresses, which never received a confirm opt-in email, so unfortunately this isn’t the issue (wish it was, simple fix!)

The account is over the active profile limit, but from what I’ve read re the Klaviyo free plan, I can’t see any indication that data collection via the default subscribe form will be blocked, just email sending (and we’re not sending any emails just yet).

Thanks, Jess
