Final Thoughts
You don’t need the biggest agency you need the right one for your stage, stack, and goals. Start with lifecycle essentials (welcome, browse/cart abandon, post-purchase, win-back), insist on a testing plan, and track revenue per recipient. Do that, and email becomes the quiet engine funding everything else.
FAQs
What’s the difference between a full-service email marketing agency and a specialist?
A full-service shop handles strategy, creative, build, deliverability, and analytics end-to-end. Specialists go deep on one area (e.g., Klaviyo flows or email design/dev) and often pair with your in-house team.
How fast should I expect results?
You can see early wins in 30–60 days from core flows (welcome, cart/browse abandon). Bigger CLV and list-health gains usually show within 90–120 days.
Which metrics should we prioritize?
Track revenue per recipient, flow vs. campaign revenue split, conversion rate, and unsubscribe/spam rates. Opens are directional; engagement and revenue tell the real story.
What budget do I need?
Most reputable email marketing agencies start around $3k–$10k/month depending on scope, volume, and creative needs. Production-only studios can be lower; enterprise CRM can be higher.
How do I vet an agency quickly?
Ask for two relevant case studies, a 90-day plan, proof of ESP certifications (e.g., Klaviyo), and their deliverability approach (SPF/DKIM/DMARC, list hygiene, ramp plans). If they can’t answer crisply, keep looking.
