Pros
Pro Multi-factor authentication available for all accounts
Mailing lists are sensitive pieces of information, especially as they contain contact information that is subject to high levels of abuse, and this enhanced protection against unauthorized access greatly aids in keeping that data secure.
Pro Freemium pricing model creates access to professional tools for startups at no cost
Since all features are available on a free plan, those looking to get a newsletter off the ground have access to the same toolkit as entities with tens of thousands of subscribers. Free tier caps out at 1000 subscribers.
Pro E-mails generated by the system are authenticated using DomainKeys, DKIM, SenderID and SPF
To reliably traverse the Byzantine system that e-mail has become, it's necessary to adhere to many protocols simultaneously. By attending to these most critical structures, you can be confident that your messages are not subject to various spam filters and blacklists. They also remove any impediments to DMARC compliance for your domain.
