Vilnius, Lithuania · Rated 5.0/5 from 1 review
Enflow Digital, located in Vilnius, Lithuania, also holds a 5.0 rating, though from just 1 review. Their hourly rate is $50 to $99, with a minimum project size of $1,000+, specializing in email marketing.
Why only 5? We only rank agencies with verified profile data and review evidence in this category — the list grows as more agencies qualify.
Consider the agency's client rating and review volume as primary indicators of reliability. Look at their specialization in relevant categories like email marketing or CRO. Geographic location can influence cost and communication. Evaluate their minimum project size to ensure alignment with your budget.
Hourly rates range from $50 - $99 to $100 - $149, with custom quotes available. Engagements can vary from hourly work to one-time projects or monthly retainers. Costs depend on the project's scope, the agency's location, and the duration of the engagement.
| Option | Best when | Typical cost | Main risk |
|---|---|---|---|
| Agency | Complex needs, budget allows | $50-$149/hr | Higher cost |
| In-house hire | Long-term needs | Salary + benefits | Limited expertise |
| Freelancer | Small projects, limited budget | $25-$75/hr | Reliability |
| Software/tools | Automating tasks | Subscription | Limited scope |
Choosing depends on the complexity of your needs and budget constraints. Agencies offer comprehensive expertise, but at a higher cost. Freelancers and tools provide budget-friendly options for simpler tasks.
Avoid hiring if your budget is below the $1,000+ minimum project size. If you lack the infrastructure to support agency work, consider smaller engagements first. Short timelines may better suit freelancers. If your needs are basic, software tools might suffice. Finally, ensure your project scope justifies an agency's cost.
For Shopify and SEO projects: eCommerce Today — strong review volume. For U.S.-based CRO needs: Lilo Social — specialized focus. For email marketing: Andzen — perfect rating. This ranking is re-scored quarterly; next update October 2026. Agencies may submit their firm for evaluation via our contact page.

Results depend on project scope and complexity, typically ranging from a few weeks for smaller projects to several months for comprehensive campaigns.
