Four hundred email tools, maybe fifteen worth your time. The five things to judge in order, the four honest signs it is time to move, and the seven-step migration that keeps your sender reputation intact.

There are more than 400 email tools out there, and maybe fifteen worth your time. The good news: at the start, the choice matters less than people think. The bad news: later it matters a lot, because moving is real work.
First, a warning about the most common mistake of all: spending three months choosing instead of sending. Someone asks which tool to use, gets seventeen answers, tries them all for a quarter, and still hasn’t sent one email. A simple tool with five flows running beats a clever tool sending nothing. You can move later. You can’t get those months back.
Does the email arrive? Nothing else matters if it doesn’t. On a 50,000 list sending weekly, the gap between 95% and 85% delivery is hundreds of thousands of missed emails a year. Ask them for their numbers. Ask to talk to customers in your industry.
Automation. Can a flow split based on whether someone clicked one link? Can it wait until a certain day? Can it test two paths against each other? Can something in your own app start it? Those four questions tell you whether it is real automation or just a timer.
Sorting people. Can you mix purchases, clicks, site visits, and your own fields in one rule? And does the group update itself in seconds, not minutes?
Connections to your other tools. Not “is there one” but “how good is it.” A store connection that passes orders over instantly is a different thing from one that waits until tonight. Check what developers can build with it, even if you don’t need that yet.
How they charge. Charging by how many contacts you store quietly pays you to keep dead ones. Charging by emails sent pays you to clean up. Watch for the add-ons too — texts, extra seats, better reports, taking their badge off your emails.
Pick three, send a real campaign through each free trial, and decide from what it felt like — not from a list of features. Choose for where you will be in a year, not where you are today. And talk to someone who has used it for a year. New users love everything.
Four honest signs. Your delivery has dropped under 90% and support can’t say why. You now need workarounds to build what you want. You pay for a lot you never touch. Or your team fights the tool more than it uses it.
Take a copy of everything. Contacts and all their fields, clicks, purchases, templates, flows — plus your do-not-send and complaint lists. You need those to sort people later and to prove people said yes.
Set up your ID first. SPF, DKIM, and DMARC on the new tool, checked and passing, before you send anything. Get this wrong and you start out in the spam folder.
Rebuild the money flows first. Welcome, cart, after-the-sale. Not all fifteen flows — the three that pay.
Send to your best people first. Only the people who clicked in the last 60 days. When they open and click, the inbox providers learn this new sender is a real one.
Add the rest in waves over two to four weeks: 90-day clickers, then 120, then everyone. Each wave should look healthy before you add the next.
Check every day. Delivery, bounces, complaints, clicks. If any of them dip, slow down. Don’t push on.
Keep the old tool running for at least 30 days. One more month of payment is cheap insurance if something goes wrong.
Expect four to eight weeks for a mid-sized list, and two to three months if you have a lot of flows. A rushed move can sink your delivery for months, and fixing that is much harder than avoiding it.
In this order: deliverability record, segmentation depth, automation logic, how pricing scales as your list grows, then the editor. Most buyers reverse that list, choose on the editor, and discover the pricing curve or the segmentation ceiling a year later.
When cost growth outpaces revenue growth, when you are working around a missing segmentation or automation capability every week, or when deliverability problems persist after you have fixed your own list and authentication.
Warm the new platform over two to four weeks. Start with your most engaged contacts at low volume, increase gradually, and keep the old platform running until authentication and volume are established. Sending your full list on day one on new infrastructure reliably lands you in spam.
