I implemented a webhook for collecting emails on my blog articles for collecting email newsletter leads. I send these emails to Hubspot as a CRM. I use NeverBounce step to make sure that the emails are valid.
I can see that each day 3-5 emails get collected, so 3-5 tasks initiated each day on Zapier for this particular zap.
Recently I saw a weird behavior, I got 1250 emails (tasks) on the Aug 29th & 900 on the Aug 30th and 800 on Sep 5th.
16th - 28th Aug: 3 tasks daily average
29th - 30th Aug: 1050 daily average
31st - 4th Sep: 4 tasks daily average
5th Sep: 850 tasks
On these spikes days, I didnt have more than 500 daily session on my website, so it doesn't make sense that these emails are from real people.
Im wondering if someone spamming my website, and if yes, how can I know it? Is there anyway that someone can reach this webhook and spam it? It feels like it these emails didnt arrive from my website and I dont understand why it happens.
Side notes:
- I have other places on the website where I have emails optin with Zapier zap that never had this issue before, all of them have stable Zap running each day.
- Webhook was implemented correctly with my developer
- All the emails look ok and not spamming + passed the NeverBounce filter.
Please let me know how can I solve it and if someone else had this issue🙏🏻
