FAQ

Common questions

Everything you might want to know before reaching out.

I'm based in Bangladesh and work remotely with US, UK, Canadian, Australian, and Netherlands clients. I keep EST/PST business hours and reply within 24 hours. Many long-term clients are US business owners β€” it works seamlessly.

I specialise in Klaviyo and Mailchimp integrated with Shopify and WooCommerce. I also work with ActiveCampaign and ConvertKit when needed, plus SMS platforms like Postscript and Attentive.

Most clients see improved open rates within 2 weeks after deliverability fixes. Revenue from flows typically starts within 30 days. One client β€” a US dog grooming store β€” went from $1,500 to $28,000/month from email within 90 days.

Both. I offer one-time flow builds, deliverability fixes, and full account audits β€” as well as monthly retainers for campaign management, A/B testing, segmentation, and scaling.

I handle strategy, design (Figma β†’ Klaviyo), and technical execution all in one place. You get one expert focused on measurable revenue growth β€” not just opens and clicks.
