In short
Which one for whom?
Apollo suits sales teams that want a large B2B database, enrichment and sequences in one tool to build their target list. Lemlist suits teams whose list is largely ready and who focus on personalised, multichannel sequences. In both, deliverability depends on your sending infrastructure.
Apollo is for
B2B sales teams building their target list from scratch that want data and sequences in one tool.

Data or sequences?
The most time-consuming part of outbound is often building the list. Apollo handles that inside the tool. If your list comes from the CRM, events or another enrichment tool, Lemlist's sequence and personalisation features come to the fore.
Infrastructure is a must in both
Without a separate sending domain, SPF, DKIM and DMARC, gradual warm-up and a verified list, both tools end up in spam.

Frequently asked questions
Can Apollo and Lemlist be used together?
Yes. Some teams use Apollo for lists and data and Lemlist for personalised multichannel sequences. Set up the CRM sync for both tools so it does not create duplicate records.
Which one has better data?
Data quality varies by country, industry and company size. The most reliable test is a small sample of your own target audience run through both tools.
Which one keeps us out of spam?
Neither on its own. Deliverability comes down to SPF, DKIM and DMARC, domain warm-up, sending volume, list quality and content. The tools' warm-up and sending-limit features help.
