Before you switch

Thinking about leaving Smartlead? Check this first.

Smartlead gives you powerful sequencing, mailbox rotation and client sub-accounts. But when campaigns start landing in spam or mailboxes keep burning, the cause is almost always the infrastructure plugged into it: the domains, the mailboxes and the DNS. Switching sequencers won't change that. Fixing the foundation will.

Inconsistent results across clients

Each client's domains and mailboxes are set up differently, so performance varies.

Mailboxes burning mid-campaign

Replacements cost extra and campaigns stall while you wait.

Hours lost on setup

Every new client means buying domains, creating mailboxes and configuring DNS by hand.

Standardise the infrastructure, and Smartlead performs the same way for every client.

The prerequisites

What every Smartlead account needs to perform

Every Smartlead account runs on the same five building blocks. Get these right and everything you do inside Smartlead works better.

1Dedicated sending domains.Keep your main company domain safe by sending cold email from separate domains.
2Real Google Workspace and Microsoft 365 mailboxes.Recipients' inboxes trust mailboxes from the major providers.
3Correct authentication.SPF, DKIM and DMARC records on every domain, set up correctly the first time.
4Warmed-up mailboxes and sensible volume.New mailboxes need time to build reputation before they send at full volume.
5A replacement plan.Some mailboxes will eventually burn. The question is whether that stalls your campaigns.

Icemail sets up all five for you, for every client, so your team can stay inside Smartlead.

The playbook

5 ways to get more out of Smartlead at scale

Let rotation do the work.

Connect more mailboxes and let Smartlead's mailbox rotation spread the volume, instead of pushing more through each one.

At $2.50 a mailbox, extra capacity is cheap.

Separate domains per client.

Never share sending domains between clients.

Spin up client-specific domains with the AI Domain Finder.

Use 2-3 mailboxes per domain.

Limits the damage if one domain's reputation dips.

Match your recipients' providers.

Mix Google Workspace and Microsoft 365 mailboxes.

Both available from one Icemail dashboard.

Replace, don't rescue.

Swap burned mailboxes instead of nursing them back.

Icemail replacements are free.

Never pay for a replacement mailbox

When a mailbox is restricted or burned, replace it free and keep every client's campaigns running.
