Top Recommendations from Pros
Industry leaders share overlooked strategies to avoid common pitfalls:
-
Match platform scale to your operations: Skip enterprise suites if you’re under 100K sends/month. Opt for mid-tier options with core automation and integrations. This cuts costs by 50-70% while delivering 80% of needed power. Save extras for content or data hires.
-
Scrub lists before import: Ditch bounced emails, opt-outs, and spam reporters from old systems. New ESPs flag risky sends fast—protect your sender score from day one. Use built-in validation tools during migration.
-
Hire migration specialists: Pros who’ve handled 5+ switches shave weeks off setup. They handle API mappings, template ports, and compliance. Budget 10-20% of annual fees for this—ROI hits in first campaigns.
-
Build internal tech skills: Train a “marketing ops” role to master APIs and workflows. Pair with agile sprints for faster testing. This unlocks advanced features without vendor dependency.
-
Prioritize timezone-aligned support: Local vendors mean same-day fixes and holiday-proof service. Attend in-person events to test rapport before signing.
Test 3-5 ESPs in a 30-day pilot. Track setup time, open rates, and support response.
Final Verdict
Right-size your ESP to current needs, clean data ruthlessly, and invest in migration expertise. Top picks for SMBs: affordable scalers like ActiveCampaign or Klaviyo. Enterprises: robust options like Braze or Salesforce Marketing Cloud. Reassess yearly—email tech evolves fast.
