SMTP access is infrastructure, not a guarantee of inbox placement. Match the plan to your sending software, expected daily volume, authentication requirements, and support needs. Confirm whether the package includes SMTP credentials only or also webmail and IMAP, then test with a small campaign before increasing volume.
Keep recipient consent, list quality, pacing, bounce handling, and domain reputation at the center of the workflow.
